Grand Seiko - Spring Drive 20th Anniversary GMT Limited Edition of 500 - SBGC231

The lion, the enduring emblem of Grand Seiko

In celebration of the 20th anniversary of Spring Drive, Grand Seiko
presents a new design in its Sport Collection. The design draws its
inspiration from the strength and power of the Grand Seiko lion,
the mark that has long been the symbol of Grand Seiko.

The lion mark was born together with the first Grand Seiko in 1960.
It reflected the ambition of the Grand Seiko team to make a watch
that was as precise, durable and beautiful as could be and revealed
the intensity of their determination. They defined their goal as making
the “king of watches”. So it was that the lion mark came to symbolize
the inner strength of Grand Seiko and inspire its watchmakers to create
the very best timepieces of which they were capable.

The case, which embodies the intense strength and dignity of lions,
is angled inwards to ensure a soft fit on the wrist. The lug of
the case looking like a lion's nail has a flat surface without
distortion by Zaratsu polishing and hairline finish. The dial has
a pattern representing the mane of the lion, which is the proof
of the king of the beasts. A second hand with glide motion unique
to the Spring Drive slides gracefully on the lion's mane.

This anniversary watch carry the lion symbol in the form of 18k yellow gold
insert in the oscillating weight, denoting the enhanced accuracy of
the specially adjusted movement (+/-0.5 seconds a day).
