Casio G-Shock Digital Mens Watch Gd-400–9D
This watch is pressure rated at 200 metres or 20bar. This means it is suitable for water sports and wearing in the surf and diving. No Watch should be used in hot water – Spa's showers etc as the hot water expands the air inside the watch breaking the seals and then when it cools it will drag in moisture into the watch movement.
