Now, I am not in the market for a watch that can go underwater; when I go swimming, I'll just take off my regular watch. However, for the diving-savvy human fish-like consumers, the Oceana Diver from Pita Barcelona is right up your alley (or stream).
This simple but stylish looking watch is fully customizable which includes the colour, dial, hands, straps (the works). Although it is still not released yet, the watch is gaining a lot of credit due to the ability to be submersed in water at a depth of up to 5000 metres, which boast a very decent distance.
The ergonomically-made watch allows for maximum comfort while involved in those underwater pastimes.
