Design
- Case and Dial
- The timepiece is constructed with an 18K white gold case measuring approximately 43.5mm in diameter. The design includes visible engravings along the case flanks, which distinguish the exterior construction. The dial features a subsidiary seconds dial located at the 9 o'clock position and a power-reserve scale positioned at 3 o'clock. The primary dial layout integrates Roman numeral markers and a prominent aperture at the 6 o'clock position, allowing for the mechanical operation of the tourbillon carriages to be observed directly from the front of the watch. The hands are manufactured from blued steel.
- Visible features
- • Blue steel hands • Engraved case side detailing • Subsidiary seconds dial at 9 o'clock • Tourbillon carriage visible through aperture
- Movement Architecture
- The movement of the Double Tourbillon 30° is calibrated as the GF02, a manual-winding caliber. Its primary feature is a double tourbillon configuration. The inner tourbillon cage is inclined at an angle of 30 degrees and completes a full rotation every 60 seconds. This assembly is mounted within an outer carriage that rotates once every four minutes, indicated by a specialized rotation indicator on the dial. This architecture is designed to address positional errors in timekeeping by averaging the influence of gravity on the balance wheel. The movement is visible through a transparent caseback and includes a 72-hour power-reserve function, displayed via an indicator on the main dial.
