ICYMI: Two New Ltd Editions From Grand Seiko

The latest from Grand Seiko, just simple, elegant watches and now made from Ever Brilliant steel, which should help keep them looking minty for a few years longer. Just 550 pieces of each model by the way. It’s hard to deduce a price from the GS website, which is being coy on that detail, let’s take a guess at £45,000 or so.

Here’s the word;

Grand Seiko introduces two watches featuring Calibers 9SA5 and 9RA2 that are made of Ever-Brilliant Steel, a type of stainless steel which is more corrosion resistant and therefore more durable than that which is commonly used in watches today. It has a brilliant white hue that enhances the beauty of the watch and is perfectly suited to the Grand Seiko Style, which was established in 1967 and whose 55th anniversary these two creations celebrate.

Calibers 9SA5 and 9RA2. At the cutting edge of horology.

The Grand Seiko Style is perfectly expressed in the new, slimmer case.

Both calibers deliver significant advances in performance, thanks to innovations that only a fully integrated manufacture could create. The Hi-Beat 9SA5 movement offers a power reserve of 80 hours while Caliber 9RA2 offers a power reserve of 120 hours with a precision rate of +/- 10 seconds per month. Remarkably, both movements are thinner than their existing counterparts and make possible slimmer cases that are true to the design principles of the Grand Seiko Style that was established with the celebrated 44GS.

A dial inspired by the stars

Every detail of the dial is designed for clarity and legibility at a glance.

Both timepieces share the same dial design which has a depth and a texture that attract the eye and take the imagination upwards towards the sky at night. The deeply etched pattern is that of the elliptical orbit of the stars as they move across the heavens. The sharp edges of the hour and minute hands provide a pleasing contrast with the gentle curves of the dial pattern. The gold-tone seconds hand extends right across the dial and its motion captures the serene passage of celestial time.

The dial of the Hi-Beat version is blue, while the Spring Drive version is in dark gray.

The see-through sapphire crystal backs reveal the beautifully finished bridges and are clear evidence of the skilled craftsmanship of the men and women of the two studios where the watches are made and hand assembled. The Hi-Beat creation is the work of the Grand Seiko Studio Shizukuishi while the Shinshu Watch Studio is the home of the Spring Drive version.

The finish of the bridges is inspired by the richness of the nature around the two studios: Shizukuishi River Finish (left) and Shinshu Frost Finish (right).

Both watches will be available as limited editions of 550 at the Grand Seiko Boutiques and selected Grand Seiko retail stores worldwide in February 2022.
