The legendary Swiss workhorse automatic movement used extensively in Sinn's 556 series and other sport watches before the transition to Sellita SW200-1. One of the most widely-used and respected automatic movements in the watch industry. Features date quickset, hacking seconds, and manual winding. Available in four grades: Standard, Elaborated, Top, and Chronometer. Sinn typically used Elaborated or Top grade movements with custom rotors. Now largely replaced by the SW200-1 in Sinn's lineup due to ETA's restricted availability.
