Grand Seiko Introduces the Spring Drive GMT SBGE248

In blue and yellow gold.

While Grand Seiko watches are classical and often formal, the Grand Seiko Sport collection is all about larger, more casual watches,

The latest addition to the Sport line is the Spring Drive GMT SBGE248, the first Grand Seiko with a yellow gold bezel and crown. Yellow gold has been widely used for Grand Seiko watch cases, including for the commemorative Grand Seiko Heritage SBGW252, but the two-tone look is a first for the brand – an indication of its conservative approach to design.

The contrast of yellow gold and blue is a tried and tested – and perhaps slightly overdone – approach for a luxe sports watch, evidenced by the popular Rolex Submariner ref. 116613.

On the new SBGE248, yellow gold is applied generously and the colour stands out. The bezel is 18k yellow gold, as is the crown, while the hour markers, hands and markings on the dial are all gilded.

Though the bezel itself is gold, the insert is scratch-resistant sapphire, just as it is on the standard Spring Drive GMT.

Size-wise the watch is identical to the standard model, with a case diameter of 44mm. The case is stainless steel, as is the bracelet.

It is powered by the self-winding Spring Drive cal. 9R66 that guarantees an accuracy of within 15 seconds a month – or half a second a day – and a power reserve of 72 hours. The incredible accuracy is thanks to the electronically-regulated, mechanical oscillator inside; the regulation in turn is governed by a quartz oscillator with an integrated circuit functioning as the brain of the entire set-up.

The calibre also boasts an independent second time zone hand that can be adjusted to local time without stopping the movement.
