Caliber 8L45 is distinguished by its exceptional accuracy and a long power reserve of approximately 72 hours when fully wound.
A thinner, longer mainspring provides this movement’s extended power reserve.
With a precision of +10 to -5 seconds per day, it is the most accurate movement to appear in a Seiko mechanical watch and was engineered to have the robustness and other qualities demanded of movements that power modern-day mechanical sports watches.
A wave motif, reflecting the refined skills of master artisans, has been applied to the rotor and bridges.
This movement brings a new brilliance to the essence of time.
