Grand Seiko Sports Champagne Automatic Spring Drive 3-Day Chronograph GMT

MPN: SBGC201

Always ready for action, the Grand Seiko Sport collection blurs the lines between function and form, allowing you to keep track of time, no matter where your next adventure takes you.

The first ever Grand Seiko chronograph model, this Grand Seiko Sport watch sits confidently within a striking 44mm stainless steel case and showcases a jet black dial with Lumibrite hands and hour markers, a date display window, a power reserve indicator, and a blue steel second hand.

A rotating bezel with 24-hour display, a screw down crown and a powerful Spring Drive movement further enhance the functionality of this watch, while a ready/start button with a half press shutter ensures the ultimate precision.

Secured with a polished stainless steel bracelet with a three-fold clasp, this performance-driven watch is water resistant to 200 meters and offers a 72-hour power reserve.

The first ever Grand Seiko chronograph, this model is powered by a Grand Seiko’s unique Spring Drive calibre, which combines the motive force of a mainspring with the high precision of a quartz watch.
The Spring Drive mechanism allows the watch to maintain precise timekeeping while also incorporating accurate chronograph capabilities, all with a maximum 72-hour (3-day) power reserve.
Grand Seiko's original glide motion is also featured in the chronograph's blue steel second hand.

The chronograph utilizes a Ready/Start button with a half-press shutter, to ensure the most precise possible operation, the chronograph start an stop buttons have a ‘ready’ stage so that the chronograph is armed by pressing the button half way.

Calibre 9R86:

Spring Drive Calibre 9R86 may well be the world's most accurate spring-driven chronograph. It delivers a precision of ±15 seconds a month, or ±1 second a day and, equally importantly, measures elapsed time not to the nearest fraction of a second but exactly, thanks to the fact that the glide motion hands stop at the very instant that the button is pressed.
The 72 hour power reserve is maintained even if the chronograph is in operation.
