Grand Seiko SBGE275 GMT 20th Anniversary Limited Edition



SBGE275 – A Spring Drive Limited Edition to commemorate the 20th anniversary of Grand Seiko’s first GMT watch.

Limited Edition: 1,500 pieces

Grand Seiko’s first GMT watch was created in 2002 and this watch celebrates its 20th anniversary. In performance and design, it has special qualities that recognize the significance of this landmark in Grand Seiko’s history.

It is powered by a specially adjusted movement, Caliber 9R16, which offers an enhanced precision rate of ±10 seconds per month. The Grand Seiko lion emblem is featured in 18K yellow gold on the oscillating weight. The dial has the rugged texture of the snow surface that can be seen in the high mountains that surround the Shinshu Watch Studio in central Japan in late winter and early spring. When the daytime temperatures start to rise and the annual thaw begins, the wind carves a unique pattern as it whips across the melting snow drifts. This ephemeral and beautiful effect is captured on the dial.

Caliber 9R16

Caliber 9R16 is specially adjusted Caliber 9R66, to deliver an even higher level of precision.
Caliber 9R66 is ±15 seconds per month (equivalent to ±1 second per day), whereas Caliber 9R16 is ±10 seconds per month (equivalent to ±0.5 second per day).
