SEIKO SKA420 Kinetic Watch
Overview
The Seiko SKA420 (5M62-0AV0) is a 40mm 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 SKA420 is currently ranked #276 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 SKA420 measures approximately 40mm wide (not including the crown) by 10mm thick and is water resistant to 50 meters. This should be sufficient for splashes, rain, baths & showers but is not recommended for swimming or 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 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 SKA420 provides the following features and complications:

- Power reserve indicator button which causes one of the hands to move to show the remaining power level
