This is Grand Seiko – 9R Spring Drive

Spring Drive is a unique watch technology. It generates energy like every other luxury mechanical watch but combines this with an electronic regulator to deliver a level of precision that no mechanical watch can match.
The development of Spring Drive was possible because Grand Seiko is one of the very few manufacturers with mastery of both electronic and mechanical watchmaking.
The Shinshu Watch Studio drives innovative ideas and novel technologies behind the ultimate quartz watches and Seiko's exclusive Spring Drive watches.
