The Seiko SKA366 is a men's kinetic dress watch featuring a two-tone TiCN and gold-tone stainless steel case and bracelet. The black dial is accented by luminous gold-tone hands and index hour markers, with a date display positioned at the 4 o'clock position. The 39.5mm round case measures 11.2mm thick and is fitted with a scratch-resistant Hardlex crystal and a skeletal exhibition case back.

Powered by Seiko's Caliber 5M62 auto-quartz kinetic movement, the watch generates electricity from the natural motion of the wearer's wrist and can store up to approximately six months of power reserve. It provides hours, minutes, seconds, and date functions and is water resistant to 100 meters (330 feet). The bracelet secures with a push-button deployment clasp and has a 20.5mm lug width.
