Longines Chronograph 1/10s
Team,
From the same owner of the fantastic Breitling collection here is an uncommon (at least for me) Longines pocket chronograph.
This watch, based on a quick research, was released to be used during the Olympic Games in Mexico 1968 (I don't know if it was really used).
On this watch, a rattrapante or double chronograph, the main seconds hand includes a vernier allowing the measurement of 1/10 of a second.
How this works, I leave this to an expert. My experience with verniers was so long ago that I don't have a clue about how it works.
One can obtain more details on Wikipedia, searching for vernier.
Cutting short, here is the watch:
1) The watch inside the case. Notice the protective case that expose the two pushers. This baby was ... used.
2) With the protective case open
3) The watch outside the case
4) A B&W version
5) A side view, exposing the controls
6) The watch adjustment control.
7) Case back (Last digit of the serial numbers masked).
(On the reflex, it's me wearing summer clothes -- Bermuda shorts)
It was fun to play with this watch. By a short and inconclusive test, the watch is keeping great time for a 1968 piece.
Amazes me how much effort the watch manufacturers put on time measure, long time ago.
Cheers,
Nilo

lovely watch, but surely Omega timed the 1968 Olympics
Omega released the Chronostop for the 1968 Olympics. Longines timed the 1972 Olympics. could it have been released then? the standard release watch then was a single button chrono with no continuous second and a single 30 minute totaliser. it is a really ...
It's a double chronograph ...
The Orange hand is activated by the main pusher and the black one is the secondary seconds hand. It operates just like a rattrapante chronograph. Cheers, Nilo

The Vernier.
Hey G. My guess on how the "attached bit on the second hand works": As Nilomis wrote, it's a vernier scale. An example of how it might work: The watch is a 36000bhp or 1/10. If you look carefully at Photo 2), you'll see that the orange second hand is a fr...

No idea ...
And I could not figure how to open it and my watchmaker was in vacations. Sorry, Nilo
In house
Nico, In-house of course as always with Longines. Cal 262 is one of Longines absolute milestone movements, and was Longines last chronometer competiton movement (stripped down to "time only" for Neuchatel chronometer competitions) in 60s. Very successful ...
Agreed on the tip of the iceberg, RDL.
I had some doubts as for the era... At this moment Longines started to outsource the movements of their Chronographs ( Valjoux, if I am not wrong ), hence my interrogation. Thanks for the information! Best, Nicolas.
This movement is from the 60's ...
I believe that Longines, among several others, went to some sort of "sunset" on the late 70's when they switched to ETA movements. Let us remember that Longines created the famous (double famous because I own one watch with this caliber) L990 in 1975 and ...
Longines calibers
yes, Longines has a long and deep history (like JLC) of in-house movements, own chronograph movemsnts (as few only- most bought in by Valjoux, Venus and/or bought directly the movement maker like Omega - Lemania or Zenith - Martel etc.) and many other own...
I like the ...
... adjustable vernier and the fine tuning for the balance. Both very useful on an accurate chronograph. We need to do a thread on watches with external fine regulation for the balance. Mostly seen on pocket watches, and now a few wristwatches like Urwerk...
About externally adjustable balance, I don't know but ...
About reflections, not porn ones, I'm a pro. Several times that I was about to post a pic I catch an unwanted reflection. Most of times is the camera but sometimes is some part of me. Great idea for a post. Lets do this soon. Cheers, Nilo
