SEIKO SHF040 Kinetic Watch
Overview
The Seiko SHF040 (5M23-6B29) is a 41mm men's kinetic watch with a stainless steel case and a black analog dial protected by hardlex crystal. It uses a 5M23 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 72 hours when fully charged and will recharge when moved.
The SHF040 is currently ranked #480 in popularity out of 510 watches in this catalog. No retailer link is on file for .com; current availability is unknown.

The case of the SHF040 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 stainless steel bezel is fixed (cannot be rotated). The gap between the lugs is 20mm and the leather band can be removed using a band removal tool to be replaced with another band.
The SHF040 provides the following features and complications:
- Second hand
- Minute hand
- Hour hand
- Day window to show the day of the week including two language choices for the day (English and either Spanish, Arabic, Kanji, Chinese, French, German, Danish or Roman Numerals). When setting the day keep turning the crown to get to the next language. On most models SUN will be red and on some models SAT will be blue.
- 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
