A new professional diver’s model with the next generation Spring Drive calibre 9RA5. This watch has formidable air and water impermiability to meet saturation diving challenges up to 600m, even with its 16mm thin case and 5 day (120 hour) power reserve.
On its classic Grand Seiko blue dial the ‘passion’ red colour power reserve indicator hand symbolises the new calibre and expresses the dawn of the next sixty years of the brand’s uncompromising artisanship and constant innovation.
Accompanied by a bracelet and a silicone strap.
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.
Grand Seiko: the relentless quest for precise timekeeping from the pinnacle of Seiko Watch Corporation’s in-house manufacture. With leading watchmaking, durability and legibility, every Grand Seiko is still handmade in Japan by elite craftsmen and women.
