A powerhouse movement featured in the Prospex Luxe, Presage Luxe, and King Seiko collections, the 6R35 caliber marked an important advance in Seiko mechanical timekeeping offering an improved and impressive power reserve of 70 hours once fully wound. Beating at a frequency of 21,600 vph and employing 24 jewels, the 6R35 movement has enough torque to power high intensity Prospex diver’s models, while being small and slim enough to keep a sleek and tailored appearance in Presage and King Seiko.
