"Ushio" in Grand Seiko Blue

The Evolution 9 Collection continues to grow. Grounded in the original Grand Seiko Style expressed in a Grand Seiko watch from 1967, the recent sports watch introductions in Evolution 9 build on enhanced legibility, wearability, and comfort. With wider bracelets and a lower center of gravity, Evolution 9 presents a further refinement of many long loved attributes of Grand Seiko design.

This year’s newest addition is a new variation of the Spring Drive diver that premiered a year ago, only this time around the black wave-pattern ushio dial and the ceramic bezel have been exchanged for another highly appropriate color, Grand Seiko blue.

Inside is the 9RA5 automatic Spring Drive movement with five days of power reserve. The 9RA5 is a next-generation Spring Drive movement whose many enhancements were designed to improve accuracy and performance. These include a new IC, dual-size barrels, and an offset Magic Lever. The movement is also slimmer and more structurally robust than previous 9R automatic movements, with an accuracy of ±10 seconds per month.
