Asset Overview

The "Magic lever" is a characteristic element found in many SEIKO mechanical watches. This mechanism is used for auto-winding of the mainspring. The back and forth motion of the magic lever forces a ratchet gear to rotate in one direction only. That gear rewinds the mainspring which is enclosed in the barrel. ![](http://c.yamahata.fr/sketchfab/Seiko_magic_lever_animated.gif) *(See the [original video](https://youtu.be/eN0uNhS3Vrg) on Seiko's YouTube channel.)* ---- The Magic Lever can also be found in the TAG Heuer [Calibre 1887](https://www.tagheuer.com/en/calibre-1887). ![](http://c.yamahata.fr/sketchfab/TAGHeuer_calibre1887_magic_lever.png)
