maison birks grand seiko heritage spring drive steel 40mm sbga375 image number 0
Spring Drive at midnight.

The deep, midnight blue of the dial is the perfect backdrop for the seconds hand that moves in the perfect glide motion that is Spring Drive’s unique signature. It has an almost haunting beauty, like the sky on a moonlit night and the continuous, silent and unhurried progress of the hand seems to add a new and intimate dimension to the relationship of time and nature.

Powered by Grand Seiko’s unique Spring Drive caliber, this model features 44GS Contemporary Design, a contemporary take on the design of the 44GS, which was launched in 1967 and formed the cornerstone of the Grand Seiko design philosophy, Grand Seiko Style.
