AQUADIVE NOS Model 77
“NOS” stands for “New Old Stock” and everything about the Model 77 lives up to that. We found a stash of steel cases from the Aquadive Maritime, a watch sold by us in 1977. We’ve updated the gaskets, dial and crystal to ensure these old watches could be ready for wet work while retaining as much of their vintage charm as possible. There’s no reason to baby this watch, which is rated for 200 meters of water resistance. A helium release valve is set on the case flank at 2:00, in case your adventures involve time in a helium-saturated diving system.
Despite its vintage roots, the NOS Model 77 is big enough to suit contemporary tastes. The stainless steel case is 41 millimeters in diameter, with a versatile end to end dimension of 48 millimeters. The black steel bezel is topped by a fitting black aluminum ring fully marked for timing up to an hourlong dive or anything else.
We offer the NOS Model 77 with a choice of two movements: a 1970s-era A. Schild calibre 1902, or a moden ETA 2836. Both are selfiwinding, though the Schild beats at a slower rate and does not offer a quickset date function, to suit those looking for a true vintage feel.
True to its era, we’ve mounted a “porthole” style rubber strap on the Model 77, just as it would have been back in the ‘70s.
