I'm glad you find it interesting
This watch as you say, is weird, strange, kind of a crossing between a bathyscaphe and a... cartoon?
Its name is Hamilton Khaki Navy Frogman Auto-Chrono (puf puf :P... lengthy name, isn't it?)
It's made of Titanium Grade (well, I don't remember very well if 5 or 3) so let me check the manual.
Powered by a reliable Valjoux 7750. I like the way it hums in your wrist when the rotor wheels freely.
Bad lighting for now, but tomorrow I will post more pictures just for you.
I like this watch because it looks like a funny, rugged adventurous watch, it's one of my "relax" watches.
The green canvas strap is really nice, it gives the watch a raw look (I also have the Ti bracelet which is the one it came with),
but almost always wear it like this.
More pics...done deal my friend.
Best regards.
