SEIKO MANUFACTURE AMANTA
The watches engine is Seiko's Spring Drive; a part electrical movement. It uses a mainspring, barrel, automatic winder and stem winding like in a mechanical watch to store the watch energy. The conventional escapement is replaced with a device that Seiko calls a Tri-synchro Regulator to regulate the unwinding of the mainspring.
