This is the Bronze SD1975 which pays tribute to the "Grandfather Tuna"or"Tuna Can" first manufactured in 1975 after a Japanese saturation diver complained that all the existing diver watches were not strong enough to withstand heavy impact and prolonged periods of deep underwater pressure.The "Tuna" was therefore designed to be the "perfect professional divers' watch" and one of its innovative features is the shroud that makes the watch extremely robust and also very distinctive.This is lovely looking watch with real presence and benefits from the following spec:
