FORTIS MARINEMASTER
You don’t see as many vintage Fortis watches around, and there aren’t that many popular models in comparison to other brands like Omega or even Eterna. However, the Marinemaster is a pretty well-known Fortis dive watch creation – and totally unrelated to its Japanese cousin.
Fortis started making water-proof wristwatches as far back as the 1940s when they released the Fortissimo. The Fortissimo line actually started in the early 1930s but the production of water-proof models only started later. These watches used Fortis-modified third-party movements that were inside of a specially designed steel case. Generally, Fortis used movements from companies like Venus, ETA, and A. Schild.

With the lilt of Irish laughter
Every day and in every way
Now forever and ever after."
