This is a user manual for SEIKO KINETIC® Cal. 3M62/5M62/5M63 watch, which has energy-saving and automatic winding functions
This manual explains the operation of Seiko Kinetic analogue watches (models 3M62, 5M62, 5M63). It describes the automatic kinetic electricity storage unit (E.S.U.) that generates power from the movement of the wearer’s arm, eliminating the need for replaceable batteries.
The guide provides step‑by‑step instructions for charging the watch by swinging, setting the time and calendar, using the screw‑lock crown, and interpreting the power‑reserve indicator. Safety notes for glass‑back cases and calendar‑setting time windows are also included.
