The design concept of BRX2-MRTB-SK-ST wristwatch BRX2-MRTB-SK-ST with hollowed out Tourbillon is that the hollowed out movement is worn on the wrist, and the square movement is placed between two pieces of advanced crystal glass to ensure that the field of vision is completely unrestricted, making the watch case disappear visually. The hollowed out dial features a revealing movement, a difficult CNC manufacturing method, and an overhead dial scale. Equipped with Swiss ultra strong night light, the pointer and high-precision display of time division information are simple but elegant and noble. Integrating the watch case and movement is also one of the most difficult challenges for watchmakers (developing BR fully hollow integrated Tourbillon movement) to make the watch closer to the original. Case diameter: 42.5 mm. Thickness: 12.5mm.
