We once took this watch out to the parking lot and ran it over with a delivery truck, then threw it in the dishwasher to scrub off the tire marks. It kept ticking without a scratch and the injection molded strap just got softer.This digital men's watch features a round green matte case. Its strap is made of matte green resin. It also comes with an Indiglo? night-light and is shock-resistant to ISO standards. This watch features a vibration alarm.
