SBGA439 gives its 40 mm stainless-steel Heritage case a midnight-blue sunray dial, a deep field set against the clean reflections of dual-curved sapphire. LumiBrite and 100-metre water resistance make the watch ready for regular wear, while the solid caseback keeps the presentation focused on the dial's colour, date, and power-reserve indication.
Behind the solid caseback, automatic Spring Drive Caliber 9R65 provides 72 hours of reserve and drives the date and dial-side reserve indication. Hacking seconds allows exact synchronisation of the fluid central hand against the midnight-blue display. The in-house movement's 30 jewels, central rotor and single barrel serve that practical arrangement, while its 32,768 Hz Tri-synchro regulation keeps the rate within one second per day.
