Quick TakeThe Grand Seiko SBGH345 is an absolute stunner, with its Ever-Brilliant Steel case shining like a beacon on the wrist. It's not just about looks, though; this watch packs some serious tech with its 9S85 automatic movement. Just peep that see-through case back and you can tell it means business. And that dial? A deep scarlet that screams "look at me" without being over the top. It's like Grand Seiko took everything we love about classic watches, cranked it up to eleven, and wrapped it in a package that feels both timeless and totally fresh. This ain't your grandpa's watch, unless your grandpa was the coolest cat on the block. With a power reserve that keeps it ticking for over two days and a design that pays homage to the legendary 44GS while forging its own path, the SBGH345 is a statement piece for those who appreciate the fine art of watchmaking. This watch just oozes cool!

DescriptionThe Grand Seiko SBGH345, belonging to the esteemed Heritage Collection, is meticulously engineered, showcasing a case and bracelet constructed from Ever-Brilliant Steel. This material choice gives the watch a distinctive bright white shimmer, while the watch's dimensions are precisely measured, with a case diameter of 40.0mm, a lug-to-lug length of 46.2mm, and a thickness of 13.3mm. A dual-curved sapphire crystal with an anti-reflective coating on the inner surface protects the dial, which is a deep scarlet, inspired by the morning sun on Mt. Iwate. The watch's total weight is 154 grams, and it includes a three-fold clasp with a push-button release for ease of wear. Furthermore, it ensures a secure fit for wrists up to 200mm in circumference. The case back, also made of Ever-Brilliant Steel and sapphire crystal, is both see-through and of screw-down design, adding an extra layer of security, while its screw-down crown enhances its water resistance rating of 10 bar.

At the heart of this timepiece lies the Caliber 9S85, an automatic movement that also allows for manual winding. The movement delivers a power reserve of approximately 55 hours and operates with a mean daily rate accuracy of +5 to -3 seconds per day. This accuracy figure is based on meticulous testing in six positions under controlled conditions over 12 days. The watch's precision is further highlighted by its magnetic resistance of 4,800 A/m, safeguarding against the detrimental effects of magnetic fields. Additionally, the movement is adorned with 37 jewels, adding a touch of refinement and contributing to its functionality. The watch embodies a modern take on the design language established by the 44GS in 1967, reflecting the sophisticated interplay between light and dark.
