SEIKO 5 SKZ577 Automatic Watch
Overview
The Seiko SKZ577 (7S36-8180) is a 38mm men's automatic watch with a stainless steel case and a black analog dial protected by hardlex crystal. It uses a 7S36 caliber self-winding mechanical movement that cannot be manually wound or hacked (the second hand does not stop when the crown is pulled out). It ticks 6 times per second which gives the second hand a smoother movement than quartz watches which tick once per second. The watch should run for up to 43 hours when fully wound and will self-wind when moved.
The SKZ577 is currently ranked #1,459 in popularity out of 2,613 watches in this catalog. This watch does not appear to be available for purchase on any .com site.

The case of the SKZ577 measures approximately 38mm wide (not including the crown) by 11mm thick and is water resistant to 30 meters. This should be sufficient for splashes & rain but is not recommended for baths, showers, swimming or diving. The stainless steel bezel is fixed (cannot be rotated). The gap between the lugs is 18mm and the bracelet band can be adjusted to fit using a link removal tool or removed using a band removal tool to be replaced with another band.
Transform the look of this watch by adding an 18mm leather band such as a Hadley Roma, Hirsch or Crown & Buckle.

- Second hand
- Minute hand
- Hour hand
- Day window to show the day of the week including two language choices for the day (English and either Spanish, Arabic, Kanji, Chinese, French, German, Danish or Roman Numerals).
