The Casio G-Shock MTG 900 is a rugged sports watch made in Japan. It is water resistant up to 200 meters below sea level. It features a shock absorbing back to protect its inner components. It also features a rechargeable battery. The battery is recharged through a small solar panel on the front of the watch. Over time, the battery will fail after many recharge and discharge cycles. In this case, the battery will have to be removed and replaced.
