SEIKO SARZ029 Automatic Watch
Overview
The Seiko SARZ029 (4R38-00H0) is a 42mm men's automatic watch with a stainless steel case and a black analog dial protected by hardlex crystal. It uses a 4R38 caliber self-winding mechanical movement that can be manually wound and hacked (the second hand stops 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 41 hours when fully wound and will self-wind when moved.
The SARZ029 is currently ranked #166 in popularity out of 210 watches in this catalog. No retailer link is on file for .com; current availability is unknown. You can see other models similar to this one on the left side of the page. By clicking the checkbox under a similar model you can compare that model with this one side-by-side. We use nearly 100 different weighted criteria to calculate which models are the most similar to one another.
The case of the SARZ029 measures approximately 42mm 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 4R38 movement.The stainless steel bezel shows a pilot slide rule and can be rotated. The gap between the lugs is 22mm 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 22mm leather band such as a Hadley Roma, Hirsch or Crown & Buckle.
