Seiko Watch Prospex 1975 Professional Divers Re Creation SLA041J1. It all began with a letter from Hiroshima. The correspondent, a professional diver, explained that no watch could withstand the stresses and strains he experienced when working at depths greater than 300m. Inspired, Seiko engineers got down to work. Years of research development paid off in 1975 with the introduction of the worlds first titanium cased divers watch: the Professional Divers 600m.
