The Grand Seiko Heritage Collection SBGP013G is a masterclass in precision and elegance, featuring Grand Seiko’s in-house Caliber 9F85 quartz movement. With a remarkable accuracy of ±10 seconds per year, this timepiece offers the precision of quartz with the craftsmanship of the highest level of mechanical watchmaking. Its calendar-linked time difference adjustment function allows the hour hand to be adjusted without interrupting the seconds hand, safeguarding its painstaking accuracy.
This model is housed in a 40 mm stainless steel case measuring 10.6 mm thick and with a lug-to-lug span of 47.0 mm. The case surfaces are meticulously finished using Zaratsu polishing to produce mirror-like flat surfaces and deep-dimensional brushed facets, giving it both visual refinement and robust structure. The dial is a rich deep blue sunray finish that plays with light across the room, complemented by multi-faceted hands and indices for maximum legibility. The curved sapphire crystal with anti-reflective coating enhances clarity, while water resistance of 10 bar and magnetic resistance of 4,800 A/m ensure this luxury watch is built to endure.
In essence, the SBGP013G offers a refined, modern everyday luxury watch—one with the sophistication of a mechanical timepiece yet the practicality and precision of quartz engineering. Whether worn in the boardroom or for elegant evening wear, it balances heritage design with elite performance.
