Caliber 4R36
The 4R36 Seiko caliber with day / date display is a mechanical caliber. The watch automatically recharges itself during wear by converting the wearer's arm and wrist movements into energy. Movement of the watch causes the main spring of the watch to be wound. This spring is the energy source. Manual winding is also possible. When the watch is fully charged, it has an energy reserve of around 41 hours. The tick number of this machine is 21,600 per hour and the watch has 24 jewels. The 4R caliber is manufactured entirely in-house.
