The Spring Drive calibre
The Spring-Drive calibre is a hybrid technology developed by Grand Seiko. Innovative as well as extraordinary: the Japanese company has mastered electronic as well as mechanical watchmaking like hardly any other brand, plus it combines the advantages of mechanical movements with the positive characteristics of quartz watches in a fascinating way. The result is the Grand Seiko Spring Drive - a watch that generates energy by itself but has an electronic regulation system. Their extremely high accuracy, therefore, characterises spring Drive watches.
