Seiko SNK375K1 Automatic Stainless Steel 21 Jewels Watch for Men - Silver

Product Description

The Seiko Mens Automatic Gold-Toned Stainless Steel Watch with caliber number 7S26 boasts high-tech Japanese automatic movement hidden behind classic analog styling. Precise 21-jewel Japanese automatic movement keeps this watch functioning without a battery: It is powered automatically with the movement of your arm. There is an automatic winding mechanism but then it does not need any hacking or hand winding to get the watch started. Automatic movements are a subset of mechanical movements that, when worn daily, do not need to be wound. Every time the watch is worn, an oscillating weight in the movement winds the mainspring, thus ensuring the mainspring remains fully wound. The Seiko automatic watch needs just to be set at the correct time and given a shake to charge up and gives you the most accurate and reliable time with a power reserve of up to 40 hours.
