Caliber 4R35

The 4R35 Seiko caliber with date display is a mechanical caliber. The watch automatically charges itself while worn by converting the wearer's arm and wrist movements into energy. Movement of the watch causes the mainspring of the watch to be wound. This spring is the energy source. Manual winding is also possible. When the watch is fully charged, the watch has an energy reserve of approximately 41 hours. The ticking number of this automatic is 21,600 per hour and the watch has 23 jewels. The 4R caliber is manufactured entirely in-house.
