Grand Seiko mechanical GMT SBGM221

This classic GMT watch combines the style that has long captivated watch lovers with an evolved Caliber 9S66 movement. The watch has a 3-day power reserve and combines the latest in hairspring technology with an escapement developed through MEMS technology to achieve high accuracy and stability when worn.

The design embodies a pure classical elegance with a box-shaped sapphire crystal, Zaratsu polished lugs, a brown leather strap, and a blue steel 24-hour hand complementing a deep ivory dial. The delicacy, strength and beauty of the movement can be enjoyed the exhibition case back.
