Patek and Rolex lovers - which watch sign are you?

Jaegermars – A fickle fusspot magpie determined to stand apart. You know and understand much about watches. A man of the world with a sophisticated taste. Competitive and great in bed.

Patestantin - You’re an old man, or a watch dealer. You’re beyond fashion knowing exactly what you want. You take a long time to decide and then stick with it. Safe, reliable, rich and once upon a time a good lover.

Swatchio – Unsure about everything in life, you're desperate for a woman.

Roltier – Insecure and conservative, you seek validation through material posessions by making an impression on people you don’t know. Clingy, you’re rubbish in bed.

Breitmega – Nervous, obsessive, wannabe divernaut with too many watches who can’t commit in a relationship. You’re poor, but one day you’ll be able to afford a proper piece.

Seikizen – You’re poor, but you’ll never be able to afford a proper watch. An accuracy freak you’re annoying. Can’t hold conversations with girls, who remain a mystery.

Vintique – Living your life in rose tinted hindsight with a house full of watches. A lot like Patestantin, but still good in the sack for the moment.

Panimo – Gullible, you like clocks and have a small one.

Sinfortima – Nobody pulls the wool over your eyes. A bit dull, you manage to live life pretty hard. Decisive, you have a big one.

Reflections on the Royal Oak Jumbo 15202st ultra thin

Unpopular and somewhat superceded in the minds of a new generation of buyers, I understand that something had to be done to this icon.  In the mid-naughties, customers wanted a bulked up look and feel, and more stage presence duly preferring the new 15300 which had overtaken sales with the mass produced divided labour line 3120.  Feeling twice the weight, with a bulky twin butterfly clasp, this design was pumped even further and carried to the  'lost in case' conclusion of the 15400.  These AP 'Submariners', stole the show with a new generation of buyers uninterested and overlooking the meaning and heritage of the 2121, let alone the the mythical mix of masculinity and daintiness present in the skin hugging thin, jewellery inspired, cut gem borne of Genta's one night of sweaty insanity in 1971.
So it took Octavio Garcia's oh so subtle and successful attention to detail to recover the manufactured case form and dial detail and date disk of the jumbo to become the Ultra Thin yet passed off the oddly misplaced thick and bulky twin butterfly clasp.  It went all collectors-only-super-success, 'the piece no one can get, but everyone has', doubling in price and becoming another victim of the distasteful symbiosis of brands and resellers consigning the last of the old freely available15202s, with three colours of dial and truly thin bracelet and clasp (oh, and a four figure price tag) to history in the backend of 2011. So if you want to keep the original aesthetic of thinness with some dial colour options in a late model, then the15202st.OO.0944.xx is your girl.  Or you have to find a NOS APPA clasp to fit and like the dial colour of your new Ultra Thin.

Straight Lug Speedmaster Bracelet Breakthrough



Problem with straight lug Speedys has always been finding a modern bracelet to fit - with no help forthcoming from Omega either..... And, not everyone wants to use the very nasty, cheap, but admittedly original, flat, stretch bracelets (7912, 1039, etc).

Dedicated research cross referencing from within the infamous Omega 'redbook' has unearthed that the 1125 bracelet with 617 end pieces not only fits the straight lug Speedmasters it is THE end piece for the case. At last we know now.

The 1125 is an old school style bracelet with the bent steel end pieces, the simple clasp with the big Omega logo stamped in and the cheesy authentic vintage rattle. It's more comfortable than my modern Speedmaster bracelet found on the modern Moonwatch (3570.50) due to more flexibility (a bit like a Seiko or Rolex Jubilee) and not least because it does not have the slab effect created by the solid end links. It's da schnizzle 19mm solution we've been waiting for. It's still available new, but maybe not for long.

Jerome Lambert Interview

Do you have anything you wish to say to the PuristS community?

Definitely because PuristS community has been historically the first internet specialized community, the first forum around the brand 9 years ago. So a long long time. The points of view that are always very interesting to the brand and it is interesting to see as well the coming along with the website with us as has created a bridge and things like that. And somehow the re-edition of the Polaris is as well the son of this long lasting common history and exchange that we had with the website and I love to see that the community is larger and larger. I love to see that there are always new people having interest in different aspects of the brand. I just can say "Long Life to the PuristS".


Rolex 904L and more

That 904L was used in Rolex watches was really never in doubt, the question was more was it the case and back? Your post doesn�t specifically confirm that, but I assume you intend it to mean it does. Is the case back 904 as well as the case? Now, that�s an interesting question�..

�Allergies due to higher nickel content? No, because they are using an ALLOY,� I don�t know your background, but unfortunately I�m afraid that betrays you�re getting a bit out of your depth on this topic. Everything metallic can be called an alloy apart from pure metals. There is pretty much no argument over the high nickel content of 904L, the question is one of �What�s the data for the nickel release?�

Nickel release: Should be no more than as follows - on one square centimetre of skin no more than 0.5 micrograms of nickel may be released within one week. This limit may not be exceeded by any product that is in direct contact with the skin for a long period of time. In some countries this is law. The strength of nickel release is not ascertained by the nickel content of a metal, but rather by its resistance to corrosion. Only during corrosion processes is nickel in the form of ions or complexes able to leave a steel structure. In very corrosion-resistant steels, nickel remains stably bound to the steel despite its possibly very high nickel content. 316L cases can operate at about 0.01 micrograms per cm2 per week (1/50 of the limit). I have no data for nickel release of 904L (anyone?) So we still haven�t answered that question. There is also the fact that people who seem sensitive to nickel pick up their rashes at release levels far below the recommended level. The way the surface is work hardened and even the texture has a significant effect on Nickel release and can make differences of 10 to 100 times locally.* So, it is just not possible to generalise the way you have that 904L will be ok or is better than 316L. These effects also go someway to explaining why it is very hard to get a solid view on the pattern of people�s nickel allergy in relation to the watch cases they wear.

Corrosion resistance: Under extreme conditions not related to watch wearing, 904L does have specifically superior corrosion characteristics to 316L, but having used 316L at up to 850 deg C in oxidising and corrosive environments professionally, I seriously doubt any watch wearer will gain any benefit from 904L other than a feel good factor, and the aesthetics of the colour and sheen. Well, unless they live for days on end at the bottom of the sea next to a lava source as the sea water needs to be warm (and I mean 60 deg C and up).

Hardness. Generalising about how the 904L cased Rolex shrugs off scratches compared to Omega based on magazine reports is also pretty worthless. Raw 904L is actually factually softer than raw 316L. The question is more �what hardness is delivered in the final products?� More a question of process than base alloy. Rolex may well have a process that delivers slightly harder cases than average whether they use 904 or 316L. Has anyone hardness tested the cases of all the leading watches in the lab? If someone can send me a suite of cases of interest, I�ll get them hardness tested, but they will have an indent on return, so only scrap ones please��..

Finally, why get so steamed up about the use of 904L? There are actually far �better� steels depending on your needs � so Rolex is not using some kind of �ultimate� anyway � it�s just their choice. Maybe Rolex should consider 2205, greater mechanical strength, similar corrosion resistance and it�s cheaper�..

I lived with a materials scientist specialised in metallurgy for more than a decade and if she saw your post she�d punch you on the nose! The use of 904L is a very emotive issue and we have to be razor sharp about the facts. Please take this in the nicest possible way, and in the spirit of �if you wouldn�t say it at a dinner party, don�t say it on ThePurists.� I come to the ThePurists because of the clear superiority of the exchanges compared to other fora, with the intention for everyone to prosper from increased knowledge. You post has flushed me out to hopefully write something useful and beneficial, but I wish the tone you wrote your original post in was more along the lines of �here is some info I�ve found,� rather than the whole �Rolex is best� tub thumping yet again, based on anecdotes and alleged authorities (which I�m getting pretty tired of).

* SOCI�T� SUISSE DE CHRONOM�TRIE NEUCH�TEL Relargage du nickel et corrosion par piq�res des aciers inoxydables. Influence de la direction de laminage P.-Y. Eschler, L. Reclaru, A. Blatter PX TECH S.A., Groupe PX, CH-2304 La Chaux-de-Fonds

the reference I posted above (Eschler et al) concluded that work hardening the surface INCREASED the rate of nickel release. Thus there is a difficult balancing act to perform here for manufacturers. Of course you can have a lower hardness on the back, higher on the front�..

Finally, 904L doesn�t appear to be a magic cure either as Patekkie has already got a reaction from his Daytona. I think all this proves is how far there is to go in understanding nickel release!

I wasn't going to write anything more on 904, but I can't let that stand.... I'm sorry but you CANNOT draw those conclusions.

In the end the 904 thread still really threw up more questions than answers and still did not really have concrete output on 904 v. 316. Even the data sets from industry studies are moderately contradictory (probably partly because of their meagre sample sizes.) My own experience, years ago, developing a surface treatment process for adhesive bonding of the then new Al-Li alloys (with durability tests for c. 1000 hours in seawater spray at 60 deg C) threw up MASSIVE variability issues and you needed huge numbers of test samples to extract statistically meaningful results. This was done because people's lives were in danger in the aircraft made from them. I'm afraid that nobody is going to get to the bottom of this Ni release issue in the foreseeable future because the study needed would be hugely expensive and nobody is going to die from a Nickel rash (touchwood) so nobody will bother!

I keep seeing hopeful conclusions drawn (I've looked on other watch websites) on the basis of people having looked up some broad properties of these materials and read "904 better than 316 in salt water. Ergo, Rolex better than everyone else�. I have already moaned about this "a little knowledge" issue being very dangerous. (Sidebar: What nobody ever bothers to report when they read these charts, is that whilst 904 is great for sulphuric acid transport, it's poor for nitric acid and in fact 316 is better and in fact 304 (a much 'lowlier' stainless grade) is probably one of the best for nitric. Etc, etc, yawn yawn....)

Bottom line? There are so many variations even in the lab tests from the alloys alone, let alone their surface properties (hardness, texture etc) from the data I've seen when added to the real world of people's body chemistry and so on, we can draw next to no meaningful conclusions at all. Well, other than,
1. Boy, this Ni release issue is way more complex than we realised.
2. The alloy composition is only as (or arguably LESS) important as several other factors - surface texture, hardness and skin secretion properties!

Once again in the nicest possible way - I am also concerned that you are participating in threads with little to no interest in other views or more importantly FACTS. Patekkie posts he got a rash off a watch with a case of 904 and you post �Thus, magazine writers and others need to quit talking about the possibility of rashes with Rolex.� Duh? Are you actually reading this stuff?

Based on your track record of posts, you can't really be given the benefit of the doubt so I'm afraid that it is either your Rolex heart overriding logic, the desire to have the last word, or try to prove that you WERE right after all that leads you to draw these repeated erroneous conclusions.

As you correctly stated, the allergic reactions are the result of the Nickel release, which is independent from the alloy's Nickel content. 904L contains about 24% Nickel, 316L 11%. The degree of Nickel release is directly connected with the material's resistance against corrosion. As a result, 904L releases in fact less Nickel than 316L. The latter's Nickel release rate is barely under the EU regulation 94/27/EC, which demands a release of not more than 0.5 mu-grams/per square centimetre per week. 904L is below that, at about 0.3x.

The material supplied to me compares (among other alloys) 14539 (B�hler A962 - 904L) with 14404 (B�hler A200 - 316L). There are two tests: the classic DMG test, which is a very quick and simple test: the test piece is wiped with a pad, containing a specific Ni reagent (Dimethylglyoxime). Nickel release is then indicated by a pink red colour. The other test is more interesting for materials that are in direct skin contact: the test material is exposed to 3x concentrated synthetic sweat for eight days, at a temperature of 40 deg. Celsius.


I just got a paper showing various test results from the Austrian steel manufacturer Boehler, who is the supplier of the steel used for the Rolex cases and bracelets.The paper is s lecture, held by B�hler technicians during the Euromat congress in 1999. I have a PDF-file, if you want, I can mail it to you.

Thanks for at least finding a data point for 904L! But, based on 316L experience, there's probably a very broad range of values of Ni release for 904L as well - depending on finish, work hardening, local stresses left in the surface, etc, the release rate has been shown to vary by 2 orders of magnitude in 316L.

If the data for the 904L is from a finished case on test then bravo Rolex, they're 70% inside the EU guideline. However, Sinn published a NI release rate 98% inside the EU limit for their standard 316L cases - their Tegiment case is even lower.

My point is only that there are massive variations here likely swamping the effect of the alloy and more to do with manufacturing process and finishing.

Adieu for now

After five years a lot of things have changed in the blogosphere. There are now a lot of us and most doing a much better job than me. It has been a long journey and it seems as you may have guessed by the posting rate that it has to end as my life has steadily taken new turns.

I've learned a lot driving the blog, one thing of interest is how google prioritises 'newness' over 'fact' – a very worrying find now that so much of our lives is driven by what google delivers forth on search or request.

Along the way, we've investigated the watch market, the grey market, shilling, how to get a deal, predicted a few pieces, dissected some designs, caught out IWC and JLC on their movements, seen appalling disloyalty, been plagiarised without credit and had also quite unbelievable, disgusting and threatening behaviour beyond belief from some senior watch executives. All because of my skaiwy lickle bwog? Oh and I like to think I had a bit of a hand in the rebirth of Polaris. ;-)

Yet, I've also learned many things from many patient and generous people - particularly former members of Watchrap such as SuitbertW and of course Dr Thomas M. Thanks also to supporters Dario, Chuck, Chris, A Fan, and others along the way. I have also been in receipt of quite astonishing graciousness and generosity from both JLC and AP. I thank you both.

Over the next few weeks I will cut down the content to the important minimum, so save what you will otherwise! I intend to keep things like comparison of JLC 1000 hours versus COSC test data, but anecdotal and diaryesque entries will disappear. Here's to you subscribers and your patience, I hope you appreciated that I deleted the ad feed to you. So for now adieu and A toute a l'heure.

Explorer II: Childhood Sweetheart Rediscovered

There’s been a lot of controversy over the direction Rolex have taken chubbing up their new case. It’ll suit some and change always taps up new markets (cf. JLC Compressor success). I recently had a chance to size up the now old-news new GMT IIc and was less struck by the podgy case so much as the awful pumped up maxi dial and hands. If Rolex wanted their new face to resemble a Prospex diver, well, then they succeeded. In doing so I think they lost their audience of fans of versatility. I don’t believe these developments allow the new versions to subtly slide under a suit cuff or dinner jacket physically or aesthetically like their forebears.

This year they have pursued the relentless rollout further by going all Kate Winslett on the Submariner in steel. Time is running out; the last of one of the great original tool watches will surely be gone soon. Long missing from the website, or e-brochure, the completely McQuool no date variant is still around co-selling alongside the inexplicably different date version. In a world of reissues at every turn, with the old school bracelet rattle and embarrassingly ill fitting quirky bent steel vintage end pieces, it’s actually pretty much the original Sub' still on sale; like finding a NOS piece in a closeout jeweller.

The only other example like this I can think of is the ‘proper’ Speedmaster Professional but even that has a modern bracelet now. Anyhow, what struck me when I was in the shop was the subtle aesthetic still afforded by my childhood sweetheart - the current Explorer 2*. The combination of the thinner bezel sunk below the crystal in side view and making it brushed silver achieves a more complex 3d effect while keeping the subdued versatility of restrained hour markers and slim case. SEL bracelet, bang up to date Parachrom movement and subtle Rolex rehaut engraving complete the perfect sleeper in the range. Perfect old case, latest internals and the best looking 40mm sports watch Rolex still makes.

*a leaked video has already shown a new orange hand version with maxi dial and hands that was ready for 2010 but delayed coming 2011 to coincide with its 40th anniversary.

Memovox International


The gorgeous new piece coming in Jan 2010 first announced by Dario here. The "Worldtime" feature is an alternative use of the central disk of the dial. The alarm disk carrries the major cities, with (in this case of the official photo) Paris corresponding to the triangle on the disk. You align the triangle with the hour hand, and you can read what time it is in the other cities of the world. However, this only works if you are in the timezone where the triangle is! I do not know if JLC plan to offer different dial options for different markets, e.g. Shanghai, KL, etc. Clearly that would be a good idea! (Of course you can choose to align any city as the relative time remain the same. London is 1 hour behind Paris etc) The downside is you lose your alarm time setting if you check a time - but you do 'interact' with the watch which has its charm.

So a good piece for checking international phone call timings in the office, much like the Geographic is, but arguably less practical in the field as a dual time watch where a 'Hometime' style watch is still better for this I think.

Chronometrie 2009 - JLC wins

Well it's great to see that as predicted enough interest has finally led to a modest return to testing watches under scientific conditions in an accuracy shootout.

Balls on the block time, and everyone who has turned up to this to be named or shamed deserves a pat on the back.

But as might have been expected there was only ever going to be one winner - Jaeger-LeCoultre taking the first two places.

Congrats to everyone at Le Sentier

Chapeau!

Watchrap 2.0 - MIA or RIP

And so I forlornly click on my link for Watchrap 2.0 and it repeats the same depressing message. "Watchrap is closed until further notice." And then, I always click on my saved login details, just in case, in hope....... "No access privilege groups are currently available." I guess only 'The 38' or so of us out there have even noticed or are concerned. I'm sure most have contacted TM, as I have, only to hear the grave news that the code of silence was broken - that what happens in Watchrap stays in Watchrap. Thus Watchrap 2.0 has been suspended until it can determined how to operate it successfully; maybe never to reopen. So we wait.

Watchrap was the last place on earth where one could discuss the finer points of everything from aesthetics to the nuances of drawing and locking angles of escapements without the incessant noisy drivel that plagues nigh on every other watch site. Oft accused of elitism, it was in fact a most inclusive watch discussion board if you gave it a chance.

It is a cliche but appropriate to state that you don't realise you're living in a golden age until it has passed and we became complacent and took Watchrap for granted. It could only get better couldn't it? And then suddenly -disaster- the last oasis of horology was taken from us.
