The ONLY Generation #4 Depollier Waterproof Wrist Watch known to exist.
The only known sterling silver model spanning all four generations.
Rolland's RGM Watch Company did a fantastic job with the movement overhaul, timing is now superb.
They installed a brand new mainspring and fixed the cannon pinion issue.
I could not be more pleased!
The movement pic is older, did not want to open the case back again.
