Fortis B-42 Marinemaster Watch Collection

by John Sealander

The classic styling on these iconic divers has often been imitated, but never equaled.

Fortis WatchesWhen Fortis introduced the Marinemaster in the 1960’s, it quickly became one of the company’s most popular and enduring designs. It’s easy to see why. The Marinemaster embodied everything the venerable Swiss watchmaker believed in. Marinemaster watches were well-made, precision timing tools that divers, aviators, and adventurers could depend on in any situation.

Fortis B-42 Marinemaster Watch CollectionOver the years, the first Marinemaster design grew to become an entire collection, linked by a common set of principles. Today’s Fortis B-42 Marinemaster Collection includes both three-hand day-date configurations and chronographs engineered to meet a wide variety of professional needs. These watches all feature a clearly marked unidirectional rotating bezel for timing dives and a durable stainless steel case that is water resistant to an impressive 660 feet.

All B-42 Marinemasters feature easy-to-read day-date windows at 3 o’clock, and chronograph configurations add an innovative oversized knurled edge to the rotating bezel, making it exceptionally easy to manipulate underwater. Like many Fortis watches, the B-42 Marinemaster incorporates one of the cleanest, easy-to-read dials on the market. In both the three-hand and chronograph configurations, it is this large, extremely legible dial that makes the watch a true professional timing tool. Some users prefer the simplicity of the three-hand versions, since the watch is so easy to read in difficult situations. Others prefer the chronograph models, with additional 12-hour, 30-minute, and small seconds subdials, for their versatile timing capabilities. Either way, these exciting 42mm masterpieces will never let you down.

Fortis B-42 Marinemasters are powered by a precision, Swiss-made automatic movement and protected by an anti-reflective, scratch resistant sapphire crystal. Some models also incorporate a clear viewing port on the case back, providing an intriguing glimpse of the intricate mechanical movement at work. B-42 Marinemaster timepieces can be equipped with silicon, caoutchouc, or top-quality calfskin straps to meet your needs. Alternately, some models can also be equipped with a solid stainless steel bracelet.

Fortis B-42 Marinemaster Watch CollectionAfter a century of watchmaking innovation, the Fortis B-42 Marinemaster Collection remains a visible and enduring affirmation of the legendary quality that Fortis has become famous for. Even the Fortis name means “strength,” and that’s a strong reason to contact an authorized Fortis dealer immediately and reserve your own B-42 Marinemaster.
