Grand Seiko Heritage Quartz GMT. SBGN011G.

A traditional-looking GMT watch with impressive technology to boot, this Grand Seiko Heritage GMT model captivates with its Calibre 9F86 quartz movement. Considered some of the best quartz movements in the world, the Grand Seiko 9F series has underpinned the Japanese watch manufacturer’s pursuit for accuracy, durability, beauty and ease, reinforcing them as one of the finest luxury watch brands in the industry. The 9F86 quartz calibre is no exception, aged and riotously tested over a period of three months to ensure the only the most accurate and best-performing components are used within this Grand Seiko GMT watch.

The Grand Seiko Heritage Quartz 9F85 cements its brilliance with a unique time adjustment function which allows the hour hand to be adjusted without the need to stop the seconds hand, a feature perfect for those crossing time zones. The 9F86 calibre also delivers an incredibly accuracy of +/- 10 seconds per year alongside sleek hands for hours, minutes and seconds, a date window at 3 o’clock and a brightly coloured arrow-shaped blue GMT hand. The handsome champagne coloured sunray dial sits at the centre of a 40mm stainless steel case kitted out with a smooth fixed bezel, screw in crown, stainless steel bracelet and screw down case back decorated with the legendary Grand Seiko lion emblem. Thanks to the screw down case back, the Grand Seiko Heritage Quartz promises a water resistant rating of 100 metres while the scratch resistant sapphire crystal glass has been especially treated with an anti-reflective coating on the inner surface to optimate the dial’s legibility.
