SEIKO Diver SBDA003 Automatic Watch
Overview
The Seiko Prospex SBDA003 "Blue Samurai" (7S25-00D0) is a 42mm men's automatic watch with a titanium case and a blue analog dial protected by hardlex crystal. It uses a 7S25 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 SBDA003 is currently ranked #332 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 SBDA003 measures approximately 42mm 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 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.
The SBDA003 provides the following features and complications:
- Second hand
- Minute hand
- Hour hand
- Date window to show the day of the month. Note that some watches may be damaged if you attempt to change the date between 8:00 PM and 2:00 AM, in which case you should change the time to be outside that range first then reset the time after adjusting the date. Check your watch manual for details.
