Franck MullerThis Franck Muller wristwatch, identified as a Cintrée Curvex Perpetual Calendar reference 6850 QPE, was produced in 2001. The tonneau-shaped case is constructed from 18K white gold with both polished and brushed finishes, measuring 34 by 47 millimeters with a thickness of 13 millimeters.
It is powered by the self-winding Calibre 1188MC movement, which features 37 jewels, a rhodium-plated finish with fausses cotes decoration, and a rotor with a platinum segment. The watch functions as an astronomic timepiece, incorporating a perpetual calendar with a retrograde month indicator, an equation of time feature, and moon phases displayed via an aperture at 12 o'clock. The dial is finished in guilloche silver with painted Arabic numerals and blued steel spade hands.
The piece includes an 18K white gold Franck Muller buckle and is secured to the wrist with an alligator-style strap.

- Case and Dial Design
- The watch features a tonneau-shaped, curved case manufactured in 18K white gold. The finish incorporates both polished and brushed surfaces, and the construction is of a two-body design. The case back is held in place by four screws, and the crystal is sapphire. Measuring 34 mm by 47 mm with a thickness of 13 mm, the watch occupies a significant profile on the wrist. The dial is rendered in a guilloche silver texture, featuring radial Arabic numerals and indexes. A peripheral track displays 1/5th seconds with additional 5-second markers on a plain reserve. Complications are managed through subsidiary guilloche dials for the day, date, leap year, and 24-hour cycle, with a retrograde sector for the months and the equation of time indicator located at the 6 o'clock position. The moon phases are viewed through an aperture at the top of the dial. Blued steel spade hands are used for indicating the time.
- Condition and Authenticity
- The auction description provides a grading assessment for the watch. It assigns an overall grade of AAA Excellent, with specific breakdown grades for the components: the case is graded as 2 (very good), the movement as 2* (very good), and the dial as 1-01 (as new). The hands are noted as original to the watch. These condition reports are provided as part of the listing documentation for the reference 6850 QPE model. No additional information regarding the watch's service history or prior ownership is provided in the source text.
- Movement and Mechanical Details
- The timepiece is driven by the Calibre 1188MC, an automatic movement. The plates are rhodium-plated and feature fausses cotes decoration. The movement contains 37 jewels and includes a monometallic balance adjusted to 5 positions. A shock absorber system is fitted, along with a self-compensating flat balance spring. The winding system utilizes a rotor that is supplemented with a platinum segment for mass. The auction description confirms that the dial, case, and movement are all signed by Franck Muller.
