Excellent condition (any marks in pictures are light patina which can be polished off easily) Aquadive Bathyscaphe 100 Bronze Limited Edition #70/100. Originally purchased March 2018. It has a light patina that, of course, can be polished off if desired. I can't detect a mark on the watch. Bronze caseback. 1000 meters water resistant.

This watch lists for almost $2000!!! You can go onto the Aquadive site and buy one on sale now for $1795. Or get this one in nearly new condition for $795 (net) + Shipping. Only in US. Plenty of very positive references over many years on WUS.

I only sell/trade within the US.
