SEIKO SKA397 Kinetic Watch
Overview
The Seiko SKA397 (5M62-0BS0) is a 41mm men's kinetic watch with a titanium case and a gray-silver analog dial protected by hardlex crystal. It uses a 5M62 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 SKA397 is currently ranked #330 in popularity out of 510 watches in this catalog. Check availability on Amazon.com.

SKA397 is only a partial model number. [learn more]
The case of the SKA397 measures approximately 41mm wide (not including the crown) by 11mm 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 titanium bezel is fixed (cannot be rotated). The gap between the lugs is 20mm and the bracelet band can be adjusted to fit using a link removal tool but may be difficult to replace with another band due to the shape of the lugs.
The SKA397 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.
- Power reserve indicator button which causes one of the hands to move to show the remaining power level
