The Seiko Brightz Ananta SRQ015 is a 43mm men's automatic watch with a stainless steel case and a black-red analog dial protected by sapphire crystal. It uses a 8R28 caliber self-winding mechanical movement that can be manually wound and hacked (the second hand stops when the crown is pulled out). It ticks 8 times per second which gives the second hand a smoother movement than a quartz watch which ticks once per second. The watch should run for up to 45 hours when fully wound and will self-wind when moved. Subdial Positions: 3-6-9. Chrono max: 720 Minutes. Chrono min: 1/4 of a Second. Tachymeter on the bezel. Telemeter on the inner bezel.
