SEIKO Diver SBGA031 Spring Drive Watch
Overview
The Seiko Grand Seiko SBGA031 (9R65-0AN0) is a 44mm men's spring drive watch with a titanium case and a black analog dial protected by sapphire crystal. It uses a 9R65 caliber movement that can be manually wound and hacked (the second hand stops when the crown is pulled out). The second hand glides continuously for a very smooth movement. The watch should run for up to 72 hours when fully wound and will self-wind when moved.
The SBGA031 is currently ranked #347 in popularity out of 751 watches in this catalog. No retailer link is on file for .com; current availability is unknown.

The case of the SBGA031 measures approximately 44mm 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 and even scuba diving. The crown screws down to help prevent it from being accidentally pulled out while under water. The titanium bezel shows minute numbering and can be rotated. The gap between the lugs is 21mm 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.
The SBGA031 provides the following features and complications:
- Second hand
