Founded in 1912 and known for producing robust and highly accurate tool watches, Fortis has made a name for itself as a watchmaker who seeks to produce some of horology’s most function-focused timepieces. While the brand hasn’t achieved mass-market penetration similar to other tool watch brands, the brand’s catalog still features some truly impressive models that get true enthusiasts excited, much like the Marinemaster ref. 8001 that we have here. Launched in the early 1970s, the Marinemaster was created to blend the robust construction of a dive watch with the accurate approach of a chronograph into one watch that could handle both tasks, diving (up to an impressive depth of 200 meters) and being used to time fast-paced events like any other chronograph of its time. Powered by the manual-wind Valjoux cal. 72 and sporting a 39mm stainless steel case with a black anodized aluminum bezel, the ref. 8001 was offered in two colorful configurations, both featuring black dials but with contrasting accents, one with blue accents and the other with orange. Offered here we have the blue variant, with blue chapter rings surrounding its subdials and blue accents within its hands. A functional watch with some unique pops of color, the Fortis Marinemaster is a vintage watch with a unique appeal that showcases the impressive ability for watches outside of the mainstream to be full of vigor and appeal.

The watch is in very good condition, with scratches and nicks visible on the case and case back. The stainless steel bezel remains well-defined, while the insert shows scratches and marks. The black dial is in excellent condition, featuring crisp text and vibrant blue sub dial rings. Little to no aging or damage visible on the dial surface. The lume plots at the hours have aged to a medium tone, while the lume in the hands is a shade lighter. The watch is fitted with a modern Tropic rubber strap and a stainless steel buckle. It comes in a generic dealer's box and includes a dealer purchase card.

A rare and intriguing watch with an appealing story that has a unique design to boot, the Fortis Marinemaster Dive Chronograph is perfect proof of just how rich the world of vintage watchmaking is once you venture outside of the main players.
