The watch is in wonderful pre-owned condition. There are some minor signs of use (mainly a few scuffs on the caseback). Overall condition is very good. The black dial with its bold Arabic numerals looks great and the automatic movement is keeping very good, accurate time. The recently serviced movement is a signed Breitling with 25 jewels, auto winding, and a quick-set date. The watch also features a screw-down crown and caseback. Made for deep diving to depths of 1000m/3300ft, this model was designed to compete with the Submariner market and was intended to be a tool watch for the professional diver. It does have the helium release valve located on the case at 10 0’clock.  The uni-directional stainless steel bezel has an illuminated marker at 60 minutes. The stainless steel case measures just over 40mm. With the crown guards, it actually wears a bit bigger. It feels solid on your wrist without being too big. Once service was completed and the case sealed we tested the case for water resistance. It passed both the pressure and vacuum test (please see the last picture). Comes on a new leather sports strap in brown and its original signed Breitling buckle.
