Prior to the return of Panerai to the market, I think that the Certina dive watches were the most “butch” watch that money could buy. Standing a massive 17.5mm proud of your wrist, this wasn’t a watch which discreetly slid under a shirt cuff. Originally used by the US Navy during the first Tektite experiments, this is a very serious diving watch.
The case is huge at 45mm wide (not including crown) x 48mm long x a massive 17.5mm thick stainless steel case with volcano-style bezel in good vintage condition with only minor scuffs and some very small nicks to the finish.
The dial is pretty much perfect, matt black with applied luminous-filled bar & square indices with orange markers at their tips and a steel framed date window. The dial still has all its original luminous material, which is still briefly light reactive. Original hands with original aged luminous on the sword hour and oversized parallel orange minute hand, and white painted sweep seconds hand with luminous rectangle at the tip. The original ultra thick flat high-pressure mineral crystal is in perfect condition without the usual scratches or dings.
The original thick ratcheting bidirectional rotating volcano-shaped elapsed time bezel is tight and clean with sharp, well defined knurling. The original black acrylic inlay shows wear and numerous marks from use–Very Good to Excellent original condition–but all numbers are intact and its sunken luminous “12” triangle is intact and has acquired a handsome patina.
The movement is the classic in house Certina 25-651, which has 28 jewels and beats at 19,800 bph. The watch bears the name DS, meaning Double Security, because the entire movment is protected from external shocks by a synthetic rubber ring which isolates it from the case, as well as the normal Incabloc system. Please note the date function on this watch is no longer working.
Dial is 95+%, case is 85% whilst the movement is 90+%.
Diameter 42mm; Lug to Lug 47.5mm; Height 17.5mm., it takes a 20mm strap and a new Certina signed blue Isofrane dive strap is fitted.
