- Case and Dial Design
- The watch features a distinctive rectangular, lozenge-shaped case constructed from 18K white gold. It is water-resistant and incorporates a polished, two-body design with a concave, stepped bezel. The winding-crown is inserted into the side of the case, and the watch is completed with a transparent back secured by screws, offering a view of the movement. The overall dimensions of the case are 34 mm by 46 mm, resulting in a pronounced, sculptural profile. The dial is presented in a navy blue finish, complemented by applied white gold dart indexes and Arabic numerals. The hands are fashioned in the "Dauphine" style from white gold. A power reserve indicator for the ten-day movement is positioned below the twelve o'clock marker, while an auxiliary seconds dial is located at the six o'clock position.
- Provenance and Production
- This watch was produced as part of a limited edition to celebrate the year 2000. According to the provided information, a total of 3000 examples of the reference 5100 were manufactured across four different metal variants: 1500 in yellow gold, 750 in pink gold, 450 in white gold, and 300 in platinum. The source notes that these white gold examples include a Top Wessleton diamond set between the lugs at the 6 o'clock position. To ensure the exclusivity of this reference, the production states that the specialized tooling used to manufacture the cases will not be utilized for future watch production. The watch is accompanied by its original box and certificate. The auction report provides an 'Excellent' overall grading but recommends an overhaul of the mechanism.
- Movement and Technical Specifications
- The watch is powered by the Caliber 28-20/220, described by the source as an entirely new Patek Philippe movement. It utilizes a double barrel system to achieve a ten-day power reserve, a technical feature the source describes as a first in the history of watchmaking. The movement is rhodium-plated and decorated with fausses-côtes. It comprises 29 jewels, nine of which are set in 18K gold chatons. The mechanical assembly includes a straight-line lever escapement and a Gyromax balance adjusted for heat, cold, isochronism, and five positions. It also features a self-compensating, free-sprung flat balance spring and a shock-absorber.
