The 40mm steel watch features a blue dial created to echo the ‘gently lapping waters’ of Lake Suwa near the Shinshu Watch Studio, where the watchmaker builds Spring Drive watches.
Not only does the dial appear to mimic waves, its color changes depending on the angle and amount of nearby lights, also echoing the experience of gazing into a lake.
As on its Evolution 9 brethren, the dial here is eminently readable. Grand Seiko cuts the hour hand at the tip and extends the minute hand right to the minute track so that the hands are more clearly differentiated than is typical on many other watches. For the same reason, Grand Seiko makes the 12 o’clock index especially wide for instant identification regardless on viewing angle.
Grand Seiko fits the watch with its excellent Caliber 9RA2 Spring Drive movement, which boasts a long power reserve of five days, or about 120 hours.
All Caliber 9RA2 Spring Drive movements are protected from magnetic fields up to an enhanced 4,800 A/m.
