A chronograph with the reliability of Spring Drive

The first ever Grand Seiko chronograph, Reference SBGC203 is powered by Grand Seiko’s unique Spring Drive caliber, which combines the motive force of a mainspring with the high precision of a quartz movement. It allows the watch to maintain precise timekeeping while also incorporating accurate chronograph capabilities and a GMT function, all with a three-day power reserve.

Inspired by a stop watch that was used in the 1964 Tokyo Olympics, Reference SBGC203 has pushers with a unique, two-stage construction. Designed with a ready stage so that the chronograph can be armed by pressing the button half way, you’ll always get an accurate start. There is also a screw lock system on each pusher that prevents the chronograph from being activated unintentionally. The deep black dial features a red-tipped GMT hand and is protected by a dual-curved sapphire crystal with anti-reflective coating.
