Simplicity, compactness and power - Spring Drive in its purest form
SBGA283G is apparently simple, and yet so clever. This Heritage Collection model houses the Spring Drive calibre: an innovative mechanism that combines the drive of a mechanical watch with the unbeatable accuracy of a quartz movement. The refined look is due to the case size of 39mm and the famous, high-quality Grand Seiko finish. For example, the indices have been raised and the champagne-coloured dial has a shine that creates optical depth in an impressive way.
