SEIKO SARB048 Automatic Watch
Overview
The Seiko SARB048 "Trek Monster" is a 40mm men's automatic watch with a stainless steel case and a black analog dial protected by hardlex crystal. It uses a 6R15 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 50 hours when fully wound and will self-wind when moved.
The SARB048 is currently ranked #198 in popularity out of 210 watches in this catalog. No retailer link is on file for .com; current availability is unknown. This watch is part of a family of six watches that are identical except for their color or strap. You can see the other variations in this family as well as other similar models 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 SARB048 measures approximately 40mm wide (not including the crown) by 14mm thick and is water resistant to 200 meters. This should be sufficient for splashes, rain, baths, showers & swimming (shallow diving) but is not recommended for scuba diving. The crown screws down to help prevent it from being accidentally pulled out while under water. The stainless steel bezel shows compass directions and can be rotated. 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.
