SEIKO SUN045 Kinetic Watch
Overview
The Seiko Prospex SUN045 (5M85-0AB0) is a 48mm men's kinetic watch with a stainless steel case and a black analog dial protected by sapphire crystal. It uses a 5M85 caliber quartz movement that cannot be manually wound but can be hacked (the second hand stops when the crown is pulled out). The watch should run for up to 6 months when fully charged and will recharge when moved.
The SUN045 is currently ranked #59 in popularity out of 510 watches in this catalog. Check availability on Amazon.com.

The case of the SUN045 measures approximately 48mm 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 stainless steel bezel shows minute numbering and can be rotated. The gap between the lugs is 24mm and the rubber band can be removed using a band removal tool to be replaced with another band.
Transform the look of this watch by adding a 24mm leather band such as a Hadley Roma or Hirsch.
The SUN045 provides the following features and complications:
- Second hand
- Minute hand
- Hour hand
- GMT hand to show the hour in another timezone
- 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.
- Power reserve indicator button which causes one of the hands to move to show the remaining power level
