The Seiko Prospex Speedtimer SSC813 is a 39 mm solar‑powered chronograph inspired by Seiko’s original 1964 sports timers. It runs on the Caliber V192 solar quartz movement (with over‑charge protection), offering up to six months of power reserve once fully charged, and maintains accuracy within ±15 seconds per month. #bezelhouse #watches #watchesofinstagram #watchuseek #wotd #watchoftheday #watchaddict #calgary #calgarysmallbusiness #beautifulwatch #yycsmallbusiness #yyclocal #seikolover #seiko
