Located beside the naval bases of Saint Petersburg, the Raketa Watch Factory has always been making watches for the Russian navy. The Raketa Amphibia?watch is designed on the basis of mythical Soviet Raketa diver watch model from the 1970s. It can go down to a depth of up to 400 metres. A scale on the rotating bezel marked in 15 minutes intervals enables the diver to control the level of oxygen in his bottle.
