The current Mechanical collection features Seiko’s revolutionary Magic Lever, an ingenious device that harnesses the energy created by the rotor as it turns in both directions, massively increasing the power transfer to the main spring while also delivering a faster winding speed. Technologies such as these eliminate the need for a battery change, resulting in the Seiko Mechanical collection being one of the greenest and energy-efficient currently offered by any timepiece manufacturer.   The Brand: Seiko   Seiko’s 135-year history has been marked by a ceaseless determination to innovate in every aspect of the watchmaker’s art. By embracing this mantra, Seiko has been responsible for a string of industry-leading advances in the technology of time, such as the world’s first quartz watch, the world’s first TV watch, and the Seiko Kinetic, the first watch ever to generate its own electricity from the movement of the wearer. Seiko are unique in that they manufacture every aspect of every watch in-house, with this ruthless pursuit of perfection even including growing their own quartz crystals and sapphires.
