CASIO G-Shock Silver/Black Atomic Tough Solar Multi-Band 5 Digital Men's Watch with Black IP Band. Model: GW810BXD-1: Casio

Atomic tough solar watches use a time calibration device that receives data such as time, date and other information from the atomic transmitter in Fort Collins, Colorado. This data is transmitted each second for a minute, and it does this three times each day to keep the time and date accurate and reliable. It's shock proof and 200 Meter water resistant, and is powered by a solar panel which converts inside or outside light into energy. So you never have to change your battery. Electro-luminescent backlight for visibility at night.
