Fortis a company founded in 1912 and still producing in the 21st century. This Marinemaster is a model from the early seventies and is equipped with the same movement as the early Daytona’s, Valjoux 72. It came in 2 colours, this is the stunning great Blue! The patina is unbelievable!
39mm, once a tool watch with chronograph and 200m water resistant. Now a nice, really nice vintage statement on maybe your wrist?
