GRAND SEIKO SLGA007 Lake Suwa 5 Day Spring Drive


Sold out.

A new Grand Seiko creation inspired by the serene blue waters of Lake Suwa

The patterned dial evokes the gentle sway of the surface, or minamo, of Lake Suwa. The dial echoes the lake’s ripples and shallow waves that create a pleasing sparkle at whichever angle the dial catches the light. The seconds hand and the Grand Seiko letters are sharply defined in a gold color and echo the morning sunrise shimmering on the lake’s surface.
The watch is powered by the new Grand Seiko Spring Drive 5 Days Caliber 9RA2, which inherits all the performance characteristics of the Spring Drive Caliber 9RA5 but the power reserve indicator is now visible through the sapphire crystal case back through which the beauty of the movement’s finishing can be observed.
This commemorative limited edition watch perfectly expresses the quiet but strong character of Grand Seiko. Its powerful hands and grooved, prominent markers ensure perfect legibility, its Zaratsu polished, distortion-free mirror finish and delicate hairline finish alternate, giving the case a quiet and harmonious glow. The case has wide lugs and a low center of gravity that ensures that the watch sits easily and securely on the wrist.

Series 9 Design for the overall look in the case, originally defined in 1967.
Powering the SLGH005 white birch, is the new 9SA5 Hi-Beat caliber with an 80 hour power reserve, dual impulse escapement and a free-spring balance.
