The Flow Tide watch from Body Glove has a screw down crown to allow for a depth rating of an incredible 200m (660ft). It also comes with luminous hands and markers, Swiss tide movement with tide indicator and moon phase, a classy stainless steel bracelet with locking clasp, and a rotating bezel. The Billy also features a PVD coating for extra strength.

Because it’s made by Body Glove, it has a hardened mineral crystal face to prevent scratches and a 2 year manufacturers warranty.
