Grand Seiko has introduced two new 37 mm Heritage quartz models set to arrive in December 2025: the SBGX357 “Skyflake” crafted from high-intensity titanium and the SBGX265 “Sunray” made from stainless steel. The pricing for the SBGX357 is SEK 48,900 (about $5,126), while the SBGX265 is priced at $2,700 according to their product listings.
Unique Designs
The SBGX357 features a light-blue dial, reminiscent of snowflakes, designed to reflect the look of wind-swept snow against a clear blue sky. It has a cool tempered blue seconds hand that adds to its wintery theme. In contrast, the SBGX265 showcases a sport-dress vibe with its smooth, distortion-free mirror surfaces and a detailed brushed finish, along with a vibrant blue dial that fits comfortably under a shirt cuff.
Materials and Durability
For the SBGX357, Grand Seiko has chosen high-intensity titanium for both the case and bracelet, making it around 30% lighter than stainless steel, while also ensuring it resists corrosion for everyday use. The SBGX265 uses stainless steel but maintains the same three-fold push-button clasp design that links the two watches together.
Both timepieces are powered by the in-house quartz caliber 9F62, which boasts an accuracy of ±10 seconds each year. This movement includes features like Instant Date Change, a Backlash Auto-Adjust system, and a regulation switch for precise adjustments. Grand Seiko claims that the battery lasts about three years, with the date display built into the movement.
Specifications
Each watch has a diameter of 37.0 mm, a lug-to-lug measurement of 44.6 mm, and a thickness of 10.0 mm. They both feature a lug width of 19 mm and a screw case back for easy servicing. The water resistance is rated at 10 bar, while both models can withstand magnetic fields up to 4,800 A/m. The SBGX357 weighs in at 80 g and is made with allergy-friendly materials for added comfort. The SBGX357 is fitted with a dual-curved sapphire crystal that has an inner anti-reflective coating, while the SBGX265 also uses sapphire crystal with the same internal treatment.
Grand Seiko has categorized these models under the Heritage Collection, with a planned release in December 2025 and options for purchasing online through boutiques.
