About this reference
The SBGF021 gives its 38 mm stainless-steel case a black Tatami-textured dial and 200-metre water resistance, creating a notably capable expression of the Heritage line. Its clear time-and-date display keeps the graphic surface readable, while the case's depth rating suits a watch designed for more than desk-bound wear.
Quartz Caliber 8J56 brings a date and date-linked hour correction to an in-house high-accuracy platform. A 32,768 Hz quartz oscillator and step motor support a stated accuracy of plus or minus 10 seconds per year, with hacking seconds for exact setting. The mechanism is deliberately quiet in operation, yet its calendar function and travel-oriented adjustment give the watch a purposeful daily rhythm.
