Ratio Freediver Helium-Safe 1000M Sapphire Automatic 1068HA90-34VA-RED Men's Watch

A vastly different watch from the expensive dive computers, it is for free divers, recreational water-sports enthusiasts and professionals alike. It is nothing more or less than a good timekeeping device, with a timer to set your dive span. The unidirectional rotating bezel does that. You need this if you want to go further. Also makes for a stylish street-wear.
