Grand Seiko Sport Collection Spring Drive GMT Chronograph 

SBGC 205

The deep black of the watch face contrasts with the gold of the hands and indices, giving this SBGC205 Spring Drive chronograph an alluringly mature gloss.

The case and band are made with High-intensity titanium, providing a scratch and corrosion-resistant finish with a 137g weight reduction, making it 30% lighter than stainless steel and a pleasure to wear.

At its core, the SBGC205 is powered by Grand Seiko’s unique Spring Drive 9R86 caliber, which combines the motive force of a mainspring with the high precision of a quartz watch, and offers the high-accuracy functionality of a chronograph.

Grand Seiko's original glide motion is also featured in the chronograph's second hand.
The chronograph utilizes a Ready/Start button with a half-press shutter, reducing mistakes and allowing for accurate starts. The button has been designed with the comfort of use in mind and produces a satisfying click with just the right resistance.
