Fortis Releases Limited Edition Of The B-42 MarineMaster Chronograph Alarm C.O.S.C
The B-42 MarineMaster is one of the most prestigious Fortis ranges of models, established already in the 40’s. Like its historical forerunner the latest model line the B-42 MarineMaster collection, which offers a Day/Date, Chronograph and the C.O.S.C. certified Chronograph Alarm, feature highly precise Swiss mechanical movements with automatic winding. It fulfils all requirements of professional sports watches.
The broad fluted turning bezel is the most recognizable trait of the entire collection. A double coated anti-reflective sapphire crystal allows perfect legibility not only underwater. The Fortis crown system improves newest Swiss technology to enjoy the comfort of water-resistance, similar as if the crown is tightly screwed. This new Fortis crown system has successfully passed extreme tests in vacuum and under specially pressurized conditions, in fresh water as well as saltwater. The three part steel case has a diameter of 42 mm and its water-resistance is tested to 200 m / 20 bar. A historic submarine motif is embossed on the case back and underlines the exclusivity of this Fortis jubilee edition.
