- Movement and Escapement
- The watch is driven by the Caliber 2879-1 movement, which features rhodium-plated surfaces finished with fausses cotes decoration. The movement includes 30 jewels and utilizes a lateral lever escapement. As a complex horological feature, it incorporates a one-minute tourbillon regulator featuring a steel cage with three equidistant polished steel arms. The mechanical regulation is handled by a monometallic balance that has been adjusted to heat, cold, and five positions. Additionally, the assembly uses a self-compensating Breguet balance spring to assist with chronometric accuracy.
- Case and Dial Construction
- The timepiece features a large, three-body case constructed from 18K white gold. It is designed with a stepped bezel and straight lugs, providing a distinct silhouette. The case is equipped with sapphire crystals on both the front and the transparent case back, which allows for visual access to the mechanical movement components. The watch is also paired with an 18K white gold deployant clasp. The white enamel dial serves as a backdrop for the watch's complications. It is decorated with luminous radial Arabic numerals and paired with white gold skeleton arrow hands that incorporate luminous tips. A 30-minute chronograph register is situated at the 3 o'clock position, while the aperture for the one-minute tourbillon regulator is positioned at 6 o'clock, which also supports the seconds hand under a polished steel bridge.
