Case

The round case is crafted from 18-karat gold. For the Lady Marine Diver version corresponding to this configuration, the nominal diameter is listed as 40 mm (excluding the crown), and the thickness is approximately 11.25 mm. These are the model specifications, not measurements of the specific watch being offered. The lug-to-lug length and the strap attachment width require direct measurement.

The case features polished sides and wide, boldly flared lugs that curve toward the wrist. Between them are central decorative elements set with diamonds. They create a distinct transition between the round case and the strap and are an important detail of this version of the model.

The wide bezel combines dark enameled fields with twelve gold segments set with diamonds. The finely fluted outer edge emphasizes its sporty design; in this configuration, the bezel is fixed. The dial is protected by sapphire crystal. On the right side is a screw-down crown with a distinctive profile, adorned with dark gemstones.

On the left side, a long plate bearing a unique identification number is secured with two screws. The case is closed at the bottom by a screw-down caseback featuring a transparent window through which the movement and the decorated balance wheel are visible. The manufacturer’s name and the reference number 8106-101 are engraved on the surrounding ring.

Mechanism

This version of the Lady Marine Diver is equipped with the Swiss-made Ulysse Nardin UN-810 self-winding movement. According to the specifications for the 8106-101E-3C/12, the movement is mounted on 21 jewels, operates at a frequency of 28,800 vibrations per hour (4 Hz), and provides approximately 42 hours of power reserve when fully wound. It features central hour, minute, and second hands, as well as a date window at the 6 o’clock position.

The oscillating weight replenishes the mainspring’s energy through wrist movements. Visible through the case back, the rotor features a decorative gold-toned surface and a band of colorless gemstones, ensuring that the watch’s jewelry-like finish is also evident from the movement side. The parameters provided refer to the model’s specifications; they are not the result of measurements of the timekeeping accuracy or power reserve of the specific watch being offered.

Strap

The watch features a brown rubber strap with a distinct, wavy texture. The repeated pattern echoes the dial’s decoration, making the strap an integral part of the watch’s design. Its matte finish contrasts with the polished gold and diamond accents at the lugs.

The contoured ends extend close to the case, and the flexible design allows the strap to conform to the wrist. The watch is secured by a folding clasp featuring a visible Ulysse Nardin emblem and an outer cover in the same color as the case.
