Grand Seiko Evolution 9 Style SBGC249

The Grand Seiko Evolution 9 Style SBGC249

A limited edition in celebration of the 15th anniversary of the Spring Drive Chronograph

This watch is powered by a specially adjusted movement, Caliber 9R96, which delivers an accuracy of ±10 seconds per month ( ±0.5 seconds per day). In addition to the time of day and date, it offers a GMT hand and a power reserve indicator. The chronograph measures elapsed time up to 12 hours and the seconds hand moves in perfect, continuous and silent glide motion as it does so. The deep blue of the dial and the bezel echo the colour of the night sky and contrasts with the brightness of the high-intensity titanium case.
