This Gérald Genta Solo Birétro wristwatch, reference BSO.L.10, is a stainless steel self-winding timepiece dating to approximately 2006. The watch features a tonneau-shaped, curved case measuring 34 x 47 mm with a thickness of 11 mm.
Its complex dial configuration includes a jump-hour aperture at the 12 o'clock position, a retrograde minute display with large Arabic numerals, and a secondary retrograde date sector at the bottom of the dial. The watch is powered by the rhodium-plated caliber GA3 movement, which utilizes a straight-line lever escapement and a monometallic balance with a shock-absorption system and hack mechanism. The case, which is water-resistant and secured by four screws, is matched with an integrated stainless steel bracelet featuring a concealed double deployant clasp.
The watch is signed on the dial, case, and movement.

- Case and Dial Design
- The Gérald Genta Solo Birétro is defined by its tonneau-shaped, curved stainless steel case. The construction of the three-body case includes concave sides and a rounded bezel, while the case back is secured by four screws. The watch measures 34 mm by 47 mm with a thickness of 11 mm. A corrector is positioned on the case band to adjust functions, and the winding crown is detailed with a border of small dots. A jump-hour aperture is positioned at the top of the dial, while a large-scale retrograde minute sector occupies the upper half. Below this, a secondary retrograde sector is dedicated to the date. Large Arabic numerals define the minute track, and steel alpha hands are utilized for the time and date indications.
- Condition and Presentation
- The auction house reports the condition of the watch according to a specific grading scale, where the watch is assigned an overall Grade A rating. Individual components have been assessed: the case is graded as 2 (very good), the movement is graded as 2 (very good), and the dial is described as 1-01 (as new). The original hands remain with the watch. The watch is presented on a stainless steel Gérald Genta bracelet. This bracelet is integrated into the tonneau case design and features a concealed double deployant clasp. The total length of the watch and bracelet is approximately 210 mm. The auction description clarifies that the watch is to be sold without a reserve price.
- Movement and Mechanical Features
- Internally, the timepiece is driven by the caliber GA3 self-winding movement. This mechanism is finished with rhodium plating and contains 21 jewels. The movement utilizes a straight-line lever escapement and a monometallic balance. To ensure the performance of the jump-hour and retrograde functions, the caliber is equipped with a self-compensating flat balance spring, an integrated shock-absorption system, and a hack mechanism for precise time setting. The movement is signed, consistent with the signature found on the dial and case. The components operate within the tonneau-shaped profile of the watch, providing the necessary torque and regulation for the multiple retrograde displays located on the dial face.
