Grand Seiko Heritage

A classic and elegant 3-day automatic

This watch expresses the classic style of models with mechanical Caliber 9S67 movements, preserving the design in every way while excluding the power reserve indicator and packing a Caliber 9S65 movement, instead. The watch has a 3-day power reserve and combines the latest in hairspring technology with an escapement developed through the MEMS technology to achieve high accuracy and stability when worn. The design embodies a pure classical elegance with box-shaped sapphire crystal glass, Zaratsu polished lugs, a brown leather strap, and a blue steel 24-hour hand complementing a silver dial.
