Description

Grand Seiko Sport Collection Spring Drive GMT

This compact Spring Drive sports model incorporates a zirconia ceramic bezel with a surface hardness which is around six times harder than stainless steel.

The Spring Drive movement, pioneered by Seiko Watch Corporation’s engineers, generates energy like a conventional mechanical watch – with a mainspring – but combines this with an electronic regulator to deliver a superior level of precision, never requiring a battery change.

In Spring Drive, the second-hand moves in perfect glide motion, reflecting the natural and continuous flow of time itself. It has a 72-hour power reserve, and a power reserve indicator on the bottom left of the dial.

Grand Seiko: beautifully, precise Japanese watchmaking, from the pinnacle of Seiko Watch Corporation’s in-house manufacture. Every Grand Seiko features signature high standards of Japanese precision, durability and legibility, handcrafted by Takumi artisans.

DESCRIPTION

Designed for underwater adventures, the Grand Seiko Sport collection is the preferred choice of today’s avid explorer, demanding function and form in equal measures.

Calibre 9R66:

In 2006, just two years after the completion of Calibre 9R65, Grand Seiko’s first 9R Spring Drive movement with GMT function, the Calibre 9R66, was unveiled.

“GMT” stands for Greenwich Mean Time, and uses a 24-hour hand (GMT hand) as the fourth hand on the watch dial in addition to the hour, minute and second hands.
