Grand Seiko keeps developing its iconic, nature-inspired design world drawn from Japan. Now the brand presents two new models in a more compact format — just 33 mm in diameter — with the classic Snowflake and Skyflake dials at the centre.
The new references SBGX359 (Snowflake) and SBGX361 (Skyflake) combine the familiar textured dial design with an all-new quartz movement in the 9F series. The result is two elegant watches where size, precision, and craft meet in a daintier proportion than previous Grand Seiko models. They join the Heritage Collection as permanent additions rather than a limited experiment.
Inspiration from the winter landscape of Shinshu
The Snowflake dial was first introduced in 2005 and is today one of Grand Seiko’s most recognisable design signatures. The inspiration comes from the snow-covered Hotaka mountains in Nagano Prefecture, visible from the Shinshu Watch Studio where many of the brand’s quartz and Spring Drive watches are made.
The characteristic texture in the dial recreates the feeling of freshly fallen snow shaped by winds across the mountain slopes. Instead of using white paint, the effect is created through an advanced process of silver-plating, clear lacquer, and several different finishes. The combination gives the dial a depth and a light reflection that changes depending on how the light falls across the surface.
The classic white Snowflake version is here joined by the Skyflake, a light-blue interpretation whose colour brings to mind snow glittering under a clear winter sky. On both models the bright dial is broken up by Grand Seiko’s characteristic blued seconds hand, which gives a clear but elegant contrast against faceted dauphine hands and a date-free, symmetrical display.
A new quartz movement in the 9F family
At the heart of the models sits the new Caliber 9F51, the first new development in the 9F series in six years. The 9F movements were introduced back in 1993 with the ambition of creating the world’s most advanced quartz movement for wristwatches. They are known for their high precision and the mechanical feel of how the hands move.
Caliber 9F51 retains the technical solutions that made the series beloved among enthusiasts: accuracy of ±10 seconds per year, a Backlash Auto-Adjust Mechanism that eliminates vibration in the seconds hand, a Twin Pulse Control Motor that provides enough power for Grand Seiko’s large hands, and thermo-compensated electronics for stable precision regardless of temperature. Each movement is assembled by hand by watchmakers at the Shinshu Watch Studio, where the quartz crystals are first aged and stabilised for several months before use.
The new construction also makes the movement more compact than previous generations. At just 26.4 mm in diameter and 2.2 mm thick — 0.6 mm slimmer than the earlier 9F61 — it enables thinner and smaller cases than before.
The smallest 9F watch yet
With a diameter of 33 mm and a thickness of 9.1 mm, SBGX359 and SBGX361 are the most compact models in Grand Seiko’s 9F collection to date. The size makes them particularly interesting for smaller wrists or for anyone who prefers a more classic proportion on their watch. At the same time they keep all the hallmarks that made Grand Seiko famous: knife-sharp indices, polished Zaratsu surfaces, a dual-curve sapphire crystal, and a dial where every detail reflects light in a subtle way.
The design thus balances traditional Japanese aesthetics with modern precision — something that has become a signature of the brand over the years. Both references are in stainless steel on a matching bracelet, priced at USD 3,200 / EUR 3,300, with continuous production starting in April 2026.

What are the new Grand Seiko 33mm models?
The SBGX359 with a white Snowflake dial and the SBGX361 with a light-blue Skyflake dial — both 33 mm stainless-steel Heritage Collection watches powered by the new Caliber 9F51, the slimmest 9F yet.
What is special about Caliber 9F51?
It is the first new 9F quartz movement in six years, measuring just 26.4 mm across and 2.2 mm thick, with ±10 seconds/year accuracy, a Twin Pulse Control Motor, Backlash Auto-Adjust, and thermo-compensated electronics.
What do they cost and are they limited?
USD 3,200 / EUR 3,300 each, and they are not limited — both enter continuous production from April 2026.
