Birches, platinum and Spring Drive in the new Grand Seiko

Wrist Watch

Grand Seiko continues the birch forest theme with the new SBGZ009. This time around, this limited edition platinum case and dial are engraved to replicate the feel of birch trunks. As usual, Grand Seiko is very accurate in geography - this is the Yachiyo Forest at the eastern foot of the Yatsugatake Mountains. First, the surface is polished (of course, this is Zaratsu polishing), and then long grooves are cut. The hands and markers are made of white gold, the second hand is hardened, but it is not blue as usual - Grand Seiko managed to make it gray.
