The Seiko caliber 6R35 is an automatic movement that is part of what Seiko refers to as the high-performance 6R series caliber. The 6R35 is considered an upgraded successor of the Seiko famous star-caliber 6R15. Apart from slightly thinner in size, the caliber 6R35 holds a power reserve of at least 70 hours, which is 20 hours more than the 6R15. To fully wind the mainspring, we will have to turn the crown a minimum of 55 times. Similar to the famous 6R15, 6R35 is now used for many Seiko iconic serious pieces including the Alpinists SARB, Prospex Sumo, and the retro 62MAS. 6R35 is one of the most reliable and robust calibers for Seiko in 2020!
