Grand Seiko Heritage SBGV239 40 mm

The Heritage SBGV239 is a 40 mm stainless-steel watch with a notably lean 10.4 mm case thickness. Its 46.2 mm lug-to-lug span, solid caseback and dual-curved sapphire crystal keep the round profile substantial without making it visually heavy. LumiBrite, a screw-down crown and 100-metre water resistance give the construction practical range, while the folding clasp and clean analogue display preserve the direct, functional character of the Heritage family.

The in-house 9F82 is a time-and-date quartz calibre operating at 32,768 Hz. It uses hacking seconds and carries a stated accuracy of +/-10s/year. In the Heritage collection, the SBGV239 shows how the 9F family translates the line's case language into a precise, low-profile everyday format.
