Seiko Presage collection:

Sublime mechanical watches from Japan. More than 100 years ago, Seiko produced Japan's first wristwatch, laying the foundation for a long tradition of great craftsmanship. To this day, Seiko watchmakers share a passion for innovation and craftsmanship in creating, assembling and inspecting Seiko mechanical watches. Outstanding craftsmanship forms the basis for the high standard of Seiko's mechanical Presage watches.

Automatic movement:

A mechanical 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 excite. This spring is the source of energy.

Caliber 4R38:

The 4R38 Seiko calibre is a mechanical calibre. 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 excite. This spring is the source of energy. Hand-winding is also possible. When fully charged, the watch has an energy reserve of approx. 41 hours. The ticking number of this machine is 21,600 per hour and the watch has 24 jewels. The 4R calibre is manufactured entirely in-house.

A mechanical watch works without a battery and has a larger deviation than Quartz, Kinetic or Spring Drive watches. For example: -15/+25sec per day.
