Get ready for undersea discovery and elegant nights on the town with this Invicta Pro Diver Skeleton stainless steel men's automatic watch, which is topped by a black-plated unidirectional rotating bezel with 23 hand set diamond-accented elapsed time markings. The diamonds are GH in color and SI in clarity. The large, round silver watch case measures 41mm wide (1.73 inches) and the back has a skeleton view window into the inner workings of the watch's automatic movement. The black dial face offers Tritnite luminous dotted markers and hands (with seconds hand), small minute indexes, and a magnified date window at 3 o'clock. The triple-link surgical grade 316L stainless steel bracelet band is joined by a fold-over-clasp-with-safety. Other features include a scratch-resistant sapphire crystal and coin-edged bezel for an easy grasp even with gloved hands. An automatic (or self-winding) watch is fitted with a device (rotor) that automatically winds the spring by using the force of gravity. It needs no battery, but it will stop if you have been physically inactive for an extended period of time--as long as you're moving, the watch will stay powered. Swiss watchmaker Abraham-Louis Perrelet invented the self-winding mechanism in 1770. It worked on the same principle as a modern pedometer, and was designed to wind as the owner walked.
Tritnite is a luminous material with an extended glow exclusively developed by Invicta in Switzerland and added to their timepiece hands and markers. When exposed to regular daylight, it will hold its glow for about 20 hours.
