Mechanical - Automatic Movement Watch (Self Winding Watch).
The quality watch that never needs a battery. How So? The Automatic Wrist Watch is wound by the motion of the wearer's arm rather than through the turning of the wind stem. If an automatic watch is not worn for a day or two, it will wind down and need to be wound by hand to get it started again. Each 3 ATM (100 Feet) Water Resistant model featured here has a Transparent Mineral Crystal Caseback and an Unidirectional Rotating Bezel with screened markers.
Available here at up to 70% savings over brand name prices.
Why a Self Winding Watch ? because... It's connects you more with time.
Highly valued -- not only among enviremental friendly people but for coniseurs of highest workmanship.
