US Exclusive Grand Seiko Sōkō Frost Becomes Available in the UK

Grand Seiko Soko Frost

The Grand Seiko Sōkō Frost, which was previously a US exclusive wristwatch is now available to buy outside of America for the first time. However, you still won’t see it on shelves everywhere because outside the US, it’s a James Porter & Son exclusive. Fortunately, James Porter & Son are based here it the UK with their flagship boutique located in Glasgow. While the Sōkō Frost has been around for a while, debuting in 2022, its launch here in the UK means it deserves a closer look.

In terms of its structure, it’s based on the Heritage 62GS, which means it has a 40mm diameter case in stainless steel. The flowing lines of the case are uninterrupted from lug-to-lug and the watch is famous for its bezel-less design, the sapphire crystal sitting directly atop the case. It’s one of the most distinctive designs in Grand Seiko’s heritage repertoire and one that they’ve been revisiting a lot in 2024 with new models like the Sakura-Kakushi.

The Sakura-Kakushi is actually a more relevant comparison that may initially appear because both that watch and the Sōkō Frost are based on the Japanese concept of Sekki, or micro-seasons. Instead of the broad terms we use in the west such as spring, summer, autumn and winter, the Japanese seasons are split into 24 micro-seasons. Sōkō is the 18th Sekki and is the period of time denoted by early frosts in late autumn heralding the coming winter. In that regard it’s actually the inverse of Sakura-Kakushi which is late winter snows on spring blossom.

Sōkō is represented on the dial through the frosty texture which appears blue in some images but is much more silver in the metal. It’s produced using a Japanese painting technique called Kira-zuri, where sparkly powder (traditionally mica) is mixed into the paint to give it a shimmery appearance.

However, while the surface might be cold and frosty, the inner workings are a frenetic flurry of activity. It houses the Hi-Beat Calibre 9S85, an automatic movement that operates at a 5 Hz frequency with a power reserve of 55-hours and an accuracy of +5/-3 seconds per day. Very impressive. It also has nice striped finishing, which you can see through the exhibition caseback.

As mentioned, the Grand Seiko Sōkō Frost is exclusively available from James Porter & Sons outside of the US, starting from March 1st. It is priced at £6,500, which is very reasonable considering the amazing quality of the movement and the gorgeous finishing of the case and dial. Although the most exciting thing about this release is the ability to actually buy this lovely watch that we once thought was locked away across the Atlantic Ocean.
