Dial and Complications

The dial is entirely pavé-set, creating a uniform surface of diamonds. It features radial Roman numerals applied in blue enamel, providing contrast against the pavé-set background. The watch functions as a Day-Date model, featuring two distinct horological complications: a day of the week indicator presented in an aperture at 12 o'clock, and a date of the month window at 3 o'clock. To enhance visibility, the date window at 3 o'clock is positioned under a signature Cyclops magnifying lens integrated into the sapphire crystal. The day indicator is presented in English. The hour, minute, and center-seconds hands are original to the piece, maintaining the integrity of the watch as manufactured in the early 2000s.

Movement and Certification

The watch houses the Rolex caliber 3155 self-winding movement. This caliber is a standard movement for the Day-Date line during this production period, capable of driving the day and date change mechanisms. The movement is officially certified as a Superlative Chronometer and has been adjusted to five positions and temperature to ensure chronometric performance. The auction description reports the movement number as 39 291 228. The movement is signed, consistent with the dial and the case markings.

Case and Bracelet Construction

The watch features a tonneau-shaped case manufactured from platinum. This specific reference is characterized by an extensive integration of precious stones, with the bezel alone set with 42 trapezoidal-cut diamonds. The water-resistant case incorporates a screwed case-back design, consistent with the Oyster Perpetual line. The timepiece is fitted with a specialized platinum bracelet that integrates further diamond decoration into the inter-lugs. The bracelet is constructed with individual links and includes a deployant clasp. It is set with 71 baguette-shaped diamonds, complementing the heavy platinum construction of the case. In total, the timepiece features 113 diamonds, representing a production focus on high-value materials. The total weight of these stones is documented as being just over 11 carats.
