The Spring Drive GMT caliber 9R66 has long been a Grand Seiko favorite but never before has it been presented in such a dramatic design.


Grand Seiko has just released new two-tone watch, the Spring Drive GMT, ref. SBGE248. Blue and gold interact on both the dial and bezel to create a watch that is perfect for the international traveler whether he is in the conference room or at the beach house.

Above the 44 mm case sits a rotating bezel with an 18k yellow gold ring over which the sapphire crystal extends, giving the watch extra protection and a quietly powerful depth. The dual curved sapphire has an anti-reflection coating both inside and out to deliver enhanced legibility. The case and bracelet are in stainless steel and the watch is 20 bar water resistant.

It’s powered by the accurate 9R66 spring drive. The 9R66 is Spring Drive GMT caliber which delivers a precision rate of one second per day and has a power reserve of 72 hours. The GMT hand can be adjusted to local time without stopping the movement so that the watch’s accuracy is maintained even when the time zone is changed.

The SBGE248 is officially estimated to arrive in September of this year.
