Squale Watch 2002 Blue Leather 2002.SS.BL.BL.PTC. Since the 1950s, the name Squale and the classic Shark logo, Squale translates to Shark, have come to mean one thing, professional dive watches. Squale introduced their first 1000m dive watch with a unique crystal on flexible mountings that didn not use or need a Helium release valve. Squale started to supply the elite corps of a large number of armed forces.
