SEIKO SKA633 Kinetic Watch
Overview
The Seiko SKA633 (5M62-0DE0) is a 42mm men's kinetic watch with a stainless steel case and a black 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 SKA633 is currently ranked #40 in popularity out of 510 watches in this catalog. Check availability on Amazon.com.

The case of the SKA633 measures approximately 42mm wide (not including the crown) by 10mm 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 screws down to help prevent it from being accidentally pulled out while under water. The stainless steel 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 or removed using a band removal tool to be replaced with another band.
Transform the look of this watch by adding a 20mm leather band such as a Hadley Roma, Hirsch or Crown & Buckle.
The SKA633 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
