I would just like to share one of my unique tool watches, a Tag Heuer Spirotechnique professional diver. The French company, La Spirotechnique is a supplier of high-end dive equipment and has co-branded with several watch companies ( Tag Heuer, Auricoste, Doxa, Dodane, Squale, etc..) which were sold in their outlets. They also supplied watches to the French navy and army.

 

You mean like this one :

 

Yes the Triton is a rare gem among dive watch collectors. Is it a big watch?

 

It is 38.5 X 43.5 not counting the lugs where the strap is fitted.

 

Dibs on the Triton.

 

Nice size. That's also a unique crown placement much like a bullhead watch.

 

It is meant to protect the crown especially for potholing and other kind of adventurous activity.

 

I like the combination of the dial, hands and bezel. A not too distant cousin of the SM 300s from the mid to late 60s.
