A Juhyo Snow Monster and Mt. Iwate-inspired mid-sized 44GS exclusive to members of GS9 Club USA

The blue dial of SBGW309 evokes wind-blown, ice-covered trees, which transform into monstrous shapes known as “snow monsters,” or juhyo in Japanese. Juhyo can be seen from Mt. Iwate on the neighboring Mt. Hachimantai, creating a distinct scene of winter beauty in Iwate Prefecture. 

The 44GS, released in 1967, was the first to define the Grand Seiko Style and has evolved into a modern interpretation with contemporary practicality. SBGW309 is paired with a stainless steel bracelet with a three-fold clasp with push button release.

Assembled by hand by the craftsmen and women of Grand Seiko Studio Shizukuishi, Caliber 9S64 is a mechanical manual-winding movement with 72 hours of power reserve and an accuracy rating of -3 to +5 seconds per day.

The SBGW309 will be exclusive to GS9 Club members at Grand Seiko Boutique Online and Grand Seiko GS9 Club events.
