SEIKO SARN001 Automatic Watch
Overview
The Seiko GMT Retrograde SARN001 (4S36-00A0) is a 40mm men's automatic watch with a stainless steel case and a black analog dial protected by sapphire crystal. It uses a 4S36 caliber self-winding mechanical movement that can be manually wound and hacked (the second hand stops when the crown is pulled out). It ticks 8 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 50 hours when fully wound and will self-wind when moved.
The SARN001 is currently ranked #117 in popularity out of 210 watches in this catalog. This watch does not appear to be available for purchase on any .com site.

The case of the SARN001 measures approximately 40mm wide (not including the crown) by 13mm thick and is water resistant to 100 meters. This should be sufficient for splashes, rain, baths, showers & swimming (shallow diving) but is not recommended for scuba diving. The crown does not screw down which increases the risk that it could be pulled out accidentally while under water. The watch has a display back to show of the 4S36 movement.The stainless steel bezel shows 24 hour time and is fixed (cannot be rotated). The second crown can be used to adjust the GMT hand. The gap between the lugs is 20mm 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 a 20mm leather band such as a Hadley Roma, Hirsch or Crown & Buckle.
