Overview
The Grand Seiko SBGX261 is a dress watch from the Heritage collection, housing the celebrated Cal. 9F62 quartz movement in a 37 mm stainless steel case. Its black dial is fitted with applied indices that catch light with characteristic Grand Seiko sharpness. The result is a restrained, formally oriented watch that demonstrates the brand's conviction that quartz can be a vehicle for true watchmaking craft.
History
Grand Seiko introduced the SBGX261 in 2017 as part of the ongoing Heritage line, which draws on the design language established by the original 1960 Grand Seiko. The Cal. 9F62 movement underpinning the watch belongs to the 9F family, a lineage Grand Seiko has developed since the 1990s to represent the highest expression of quartz timekeeping. The 9F calibre is widely regarded among collectors as one of the most accurate and finely finished quartz movements in regular production, lending the SBGX261 a credibility that transcends the quartz-versus-mechanical debate.
Notable points
- Cal. 9F62 quartz movement offers exceptional accuracy, typically cited at ±10 seconds per year under standard conditions.

- Applied indices on the black dial are finished to Grand Seiko's exacting Zaratsu-polishing standards, producing crisp, mirror-like edges.
- Stainless steel case surfaces combine high-polish and brushed finishing, a hallmark of Grand Seiko's hand-finishing tradition.
- Part of the Heritage collection, which references the aesthetic codes of the first Grand Seiko reference from 1960.
