## Description

This stylish automatic watch by Seiko features a clean and simple timepiece. This is a perfect watch for everyday wear. Hidden behind the Seiko Men's Automatic Stainless Steel Watch's classic analog design are high-tech progressive elements like a day and date function in two languages (English and Spanish) and precise 21-jewel Japanese automatic movement, a feature that means this watch never needs batteries or winding; it is powered automatically by the movement of your arm. Time of day is displayed on a gray analog dial that showcases luminous silver-toned hands and luminous silver-toned baton and Arabic hour markers. The dial also features a day and date window at the three o'clock position, and is protected by a Hardlex crystal and backed by a stainless steel case. Keeping all of this securely on your wrist is a stainless steel link bracelet that closes with a double-push-button fold-over safety clasp. Other features include a custom crown at the four o'clock position and water-resistance to 99 feet (30 meters).

Classic!

### ⭐ Slows down suddenly for no apparent reason
*by A***N on November 26, 2024*

I bought this watch to replace a Seiko kinetic on which the band broke, but had worked flawlessly for about 20 years. This replacement watch, after about 6 months, has had three instances in the last month where it loses 30-45 minutes over about a 4 hour time frame. I called Seiko customer service, and was told "unless you're doing 200 jumping jacks, the capacitor is not going to stay charged." I am fairly active through the day, and certainly don't feel I should need to do 200 jumping jacks just to keep it operational and reliable. Also, the watch runs overnight for ten hour stretches without any kinetic input and keeps excellent time. Although I have been a long time fan of Seiko, the response from customer service was condescending and lackluster at best, and not what I would expect from what should be a world class company. I am going to give the watch another chance, specifically paying attention to my movement levels, but if it slows again, I am done with this watch and will replace it with another brand.
