Tissot PRC 100 Solar

Twelve flat faces around the bezel are what people remember about the PRC 100, and the 39 mm case gives them room. Steel throughout, 9.22 mm deep, with flat sapphire over a green dial that carries Super-LumiNova® hands and a date. The Lightmaster movement runs on light alone, charging from a window or an office ceiling and flagging when energy drops low. The 20 mm lugs release without tools, so leather, mesh or rubber all fit. Water resistant to 100 m. (Reference T151.422.11.091.00 / T1514221109100)
