Grand Seiko Sports Black Automatic Spring Drive 3-Day Chronograph GMT SBGC203
Proving that high-performance timekeeping can be incredibly stylish, the Grand Seiko Sport collection will allow you to enjoy expert precision and striking aesthetics.
The first ever Grand Seiko chronograph, this Grand Seiko Sport watch is presented in a striking 40mm stainless steel case and protected by sapphire crystal glass.
Powered by a unique Spring Drive movement, the black dial is equipped with a 24-hour hand, three chronograph sub-dials, a date display window, and a power reserve indicator.
Presented on a stainless steel bracelet with a three-fold clasp, this luxurious model is water resistant to 100 meters and offers a 72-hour power reserve. This high-performance model benefits from a ready/start button with a half-press shutter, allowing for accurate starts and enhanced precision.
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.
