The Seiko 5 Men's Automatic Black Strap Black Dial Watch is an elegant watch with the benefit of automated motion. An uniquely developed, black dial features white Arabic numbers marking the hours on an inner circle and the minutes on an external circle, while little, bar indexes surround the dial on an outside minute track. Silver-tone hands with luminescent fill make it simple to inform time day or night, and the slim pre-owned is detailed with a red accent. For added benefit, a day and date display are set at 3 o'clock. The polished stainless-steel case extends to fulfill the black nylon strap, which covers easily around the wrist and fastens with a conventional buckle. Water resistant to 30 feet (100 meters), this high-performance watch is ideal for everyday wear.This is an automated mechanical watch. Automatic watches do not run on batteries, instead, they are powered immediately by the motion of the wearer's arm. If the primary spring in your automated watch is not wound adequately, timekeeping might become less precise. In order to keep precision, use the watch for 8 hours or more daily, or manually wind the primary spring by turning the crown. When not in usage, automated watches might be kept charged with an automated watch winder-- a watch storage system which might be acquired independently.
