SBGC251 measures 45.3mm in diameter, 15.8mm in thickness, and 52.6mm lug-to-lug. The case and bracelet are made of High-Intensity Titanium, which is 30% lighter than steel while being more impervious to scratches and corrosion. The bezel rotates in both directions without a click, and has a sapphire insert with a 24-hour scale. The chronograph pushers have been made smaller while remaining perfectly tactile.

The dial is feature-rich and functionality is high. The size of the Evolution 9 Style hands and indexes makes reading the time clear, and legibility is enhanced with LumiBrite on the hands, indexes, and bezel. The light-blue GMT hand allows tracking time in another time zone, and SBGC251 can track a total of three time zones.

Powered by caliber 9R86, SBGC251 delivers precision in measuring time and elapsed time (up to 12 hours).
