Jaeger-LeCoultre

If I tell you " Jaeger LeCoultre Chronometers ", what immediately comes to your mind? There are chances you think about this: The Geophysic is the most famous of them, the most sought after, followed by the Geomatic, and the funky Master Mariner Chronomet...  

.. as a new page in LGM's chronometry archives, I suppose. - Thank you for this captivating write-up, getting very near to the core of an almost " mysterious" watch & reference There are several design properties, which IMO play a sort of double role, bei... 

Be sure That Iwill come back on the 1000 hours control... That Is avery interesting topic. Best Nicolas

It is extremely attractive on your wrist, and I really do not concentrate on the fact that is is YG. It had to be really exciting to touch this one in the metal. I would love to see this one as a family picture with your Geophysic. Best, Joe

The Watch is not mine... So, the family picture will be difficult to do... Best, my dear Joe. Nicolas

1958 was a year of chronometers in honor of International Geophysical Year. And this one is quite lovely indeed! I really appreciate your thoughtful and interesting review here.

pictures. Interesting history indeed, I find it strange however that it is so difficult to find the sources and the history of watch even from the manufacturer? Cheers Francois

pedantic or, shall we say overscrupulous? Your title says "The missing link in the JLC Chronometry History"....but! This is not a JLC! It is a LeCoultre! More surprisingly, and please forgive me, as you know I am a neophyte, the crown bears the JL logo! T... 

Very rare indeed and with an interesting story. Actually, this one watch from a friend you have pictured here is probably the only one to have surfaced so far. In 15 years of closely monitoring all well known markets, it is the first and only time I have ...  

And lastly, here is the display card that was part of a 125th anniversary set. The card was to be installed by the AD to create a nice decor and highlight the watch features. This is the display card of the Chronometer: ...  

.. really enjoyed your ads and your deliberations; - a little bit like a detective story .. One little Q may be allowed: - was this dial shown on your ads & Nico's post the only dial configuration ? Thank you for your share Best, hs

OK, now after looking back at the published material we have altogether, I can see this '2 dials possibilities' for the Chronometer (so when discarding the 14k non-chronometer MM which would be another watch altogether). It seems that the early material p...  

.. those 3 Captains + the piece(s) surfacing, appear to be an important cornerstone.. For me, it was interesting that seen in an ad, by no means would prove the physical existence of the watch, in a given special configuration Again thank you kindly for y... 

I knew that the Master Mariners existed, but didn't know they went back to the Jubilee year of '58. I like the "torpedo"-esqe hour indices. Funky, but like a gnarled tree, give it real "character." Thanks for posting. -Dean

Pictures from an Ebay auction back in December 2004, no clue what it sold for. These MM Chronometer watches are indeed rare birds, wonder if these did not sell well due to the high prices since the watch was adjusted and most likely cased in Switzerland. ...  

Those long lasting hard drives, what would we do without them ! You just confirmed therefore that both Dial 1 and Dial 2 made it to actual watches past the paper. It seems that we are moving step by step towards discovering this Euro / US Chronometer 'sto...  

Naming it "Master Mariner Chronometer" will cause confusion since the Cal. 906 Chronometer is from the Master Mariner line as well. ;) Personally tend to simply call it 476 Chronometer. The case back on the former Artcurial auctioned Watch, Nico shows us,... 

Thank you for this great post, my friend! :) I see Clavi already added all the documents on this one. Still haven't seen this one live... Best Blomman
