This year, the independent Swiss watch brand Brellum expands its flagship line Duobox with the addition of new gold edition models. The new collection presents new dials, new Nebur Tec straps and steel bracelets, but retains the features that have made it so successful.
The Duobox Gold Edition features a 41.80mm stainless steel case. The case middle is surmounted by an 18-carat solid gold bezel. The watch is equipped with box type sapphire crystal glass, which offers perfect readability of the new dials with multiple finishings.
The sapphire crystal case-back enables the wearer to admire the splendid Valjoux 7750 automatic chronograph movement, entirely decorated and officially certified Chronometer by the COSC.
Rated for a power reserve of 46 hours, the movement features decorations like Côtes de Genève, blue screws and perlage.
