Horological Meandering

Team, Here is a watch that I never saw another and this, as is my standard procedure, raises some concerns. First of all, let me describe how it works: The pusher at 2 starts and stops the chronograph but when it stops, it continues to work, like the Chro...  

Nicolas, Explain more about if this movement is suppose to work as I described? And the case? What is wrong? Thanks, Nilo

I am not sure about the case because I saw several with simpler lugs. But I am not an expert, and didn't see all the variations on this movement, which was born a the end of the 20ies, early 30ies, if I remember correctly. It is a 27 mm big movement, beat... 

if someone ask me last week my answer was "Omega invented the Chronostop". Lots to learn. Thank you my friend, Nilo

Hi Nicolas, The first wristwatch of this kind (montre strop) was the GP Mimolypic in 1936. After that you have dozen of such watches. The Omega came much later. Regarding the Lemania you mentioned, it is a different thing. It resets the second hand and fu... 

Do you have any picture of the Mimolympic,to share? Not that I want my wish list to be longer, but... ;) Best, Nicolas

This one ( in the ad )?

I like the vintage military look. Nice piece! The fact that it's a chronograph makes it really special because it has a nice clean look. The fact that it's a monopusher is icing on the top of the cake.

This model came in different sizes (have seen from 32/33 to 36/37mm - most are small), and different forms (round pusher also). I myself had this 12.68z model with exactly the same lugs, and the watch was confirmed by Longines. So, the case should be all ... 

After I posted here I was informed that a dear friend acquired this Longines and it will be great news that his watch is correct. Thank you very much, Nilo

A very nice watch and rare in the larger size case. As has already been said this is a Longines 12.68z movement onto which they added a chronograph module which creates a constant running chronograph with a flyback function, designed around 1938. You get ... 

Ubik, Perfect. My friend will be very happy with your information. Cheers, Nilo

Hi, long time lurker on this forum and fan of these 12.68z stop seconds. This is a lovely example of the center minute (red hand, replacement perhaps) variety, mid 1940's I'm guessing. Here are my two: A 33mm early 1938 UK possible military and a 38mm 194...  

Looking forward to reading more from you! Best, Nicolas

appreciate the welcome, Nicolas; Ive followed your JLC posts with great interest and will summon the courage to add my military examples to one of the (your) next posts.

A little info would be appreciated. Is this worth sending to the factory for cleaning? ...  

He is a Longines expert. Thanks, Nilo

It\'s a lovely watch worth servicing, (but sending to Longines will be very expensive) though its quite small -31mm, I believe- and getting parts for the 12.68z chrono difficult without buying a donor watch.
