This classic GMT watch combines the style that has long captivated watch lovers with an evolved Calibre 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.
Calibre 9S66 has all the performance of the most standard automatic movement of the 9S mechanical models — Calibre 9S65 — but comes with the addition of the GMT function.
Pulling the crown out by one notch enables the hour hand to be adjusted without stopping the minutes or second hand so that the accuracy is not compromised.
The watch is the embodiment of the Grand Seiko pursuit of high accuracy, maintaining exceptional precision in both the essential time display and the GMT function.
