The Grand Seiko SBGM255G captures the essence of refined watchmaking with its elegant lines and advanced mechanical movement. Housed in a 39.5 mm stainless steel case with a comfortable 46.9 mm lug-to-lug length and a 14.1 mm thickness, the watch strikes a balance between presence and wearability. Its polished surfaces benefit from expert finishing, while the domed sapphire crystal with anti-reflective coating ensures a clean, clear view of the beautifully detailed dial.
Inside, SBGM255G is powered by the in-house Caliber 9S66 automatic movement, offering a generous 72-hour power reserve and impressive accuracy of plus 5 to minus 3 seconds per day when regulated in controlled conditions. A blue-tempered GMT hand enables tracking of a second time zone, making this watch ideal for frequent travellers or those needing dual-time functionality. A date window at three o’clock completes the practical, elegant dial layout.
With 3 bar water resistance and antique-style box sapphire crystal, the SBGM255G leans toward dress and travel use rather than sporty diving, but its robust movement and craftsmanship make it a versatile companion for everyday elegance and journeys abroad. The watch’s understated sophistication, combined with Grand Seiko’s legendary attention to detail, renders it a standout for those who value classic design with mechanical refinement.
