Case and Dial Design

The Ulysse Nardin Marine Chronograph is defined by its robust 40 mm stainless steel three-body case, which incorporates both polished and brushed surfaces. It is finished with a distinctively ridged bezel and straight lugs. Functional features include a dedicated case back fixed with six screws, alongside a screwed-down winding crown and chronograph pushers, which contribute to its specified water resistance of up to 100 meters. A sapphire crystal protects the dial, ensuring durability for the timepiece. The black dial utilizes a high-contrast layout, featuring applied white Arabic numerals paired with luminous dots for legibility. Timekeeping and chronograph functions are displayed via luminous white "moderne" hands. Chronographic data is managed through two subsidiary dials indicating 30-minute and 12-hour registers, while an outer tachometer graduation rings the perimeter. Calendar functions include a large double-disc date aperture at 12 o'clock and a secondary aperture indicating the current month, situated between the 4 and 5 o'clock positions.

Condition and Included Accessories

The auction description reports the watch to be in good overall condition. According to the internal grading system used for the catalogue, the case and movement are both classified as 'Very good', while the dial is rated as 'As new'. The original hands remain intact on the watch, and the assembly is complete with its original stainless steel Ulysse Nardin buckle, which secures the strap. The timepiece is accompanied by its original fitted box and a certificate, which provides documentation for the lot. The report indicates that the physical state of these elements is consistent with a piece produced circa 2000, and no major deficiencies are noted in the provided assessment.

Movement and Mechanical Specifications

At the heart of the timepiece is the Calibre UN 51, a self-winding mechanical movement designed for the marine chronograph series. With a total of 49 jewels, the caliber utilizes a straight-line lever escapement and a monometallic balance to ensure timekeeping accuracy. The integration of these components allows for the efficient operation of the chronograph and calendar complications, which the manufacturer notes are signed on the movement itself, alongside the case and dial.
