Seiko Presage Collection

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

Kaliber 4R38

The 4R38 Seiko caliber is an automatic caliber. The watch automatically charges itself when 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. Hand winding is also possible. When the watch is fully charged, it has an energy reserve of approximately 41 hours. The tick number of this automatic is 21,600 per hour and the watch has 24 jewels. The 4R caliber is manufactured entirely in-house.

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