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
