Ulysse NardinThis Ulysse Nardin marine chronometer, identified by movement number 010497, was manufactured in the 1970s. Housed in a three-tier mahogany case, the instrument features brass-bound corners and folding handles for transport.
The movement is powered by an electric remontoire system and incorporates 21 jewels. Its escapement is of the straight-line lever type, fitted with a monometallic balance and a self-compensating flat balance spring. The unit also includes a shock absorber and a micrometer regulator, and is protected by a Perspex cover. Time is displayed on a white painted dial featuring Roman numerals and an outer minute track, with blued steel spade hands indicating the hours, minutes, and center seconds.
The chronometer is mounted within a gimballed brass bowl featuring a machined-edge bezel, while the middle section of the case bears an engraved brass signature plaque. The dial, case, and movement are all signed by the maker.

- Case and Exterior
- The object is presented in a three-tier mahogany box. The construction incorporates brass-bound corners, which serve as structural reinforcement and aesthetic detail. To facilitate handling or secure mounting, the case is equipped with folding handles. The middle section of this mahogany structure features an inset brass plaque, which acts as the primary signature plate for the instrument. The internal display utilizes a gimballed brass bowl. This bowl is designed to maintain a level position regardless of the orientation of the mahogany box, a configuration for marine-based timekeeping. The bowl is finished with a machined-edge bezel, providing a grip for opening or adjustment. A clear Perspex cover is provided to protect the dial and hands from the environment.
- Dial and Timekeeping
- The time is displayed via a white painted dial. It is indexed with radial Roman numerals for the hour markers and includes an outer track for the minutes. The time is indicated by a set of blued steel spade hands, which contrast against the white ground of the dial. The presence of a center-seconds hand allows for the tracking of smaller time increments. The movement driving these hands is an electric remontoire system. It operates at 21,600 vibrations per hour and is powered by a battery. The system includes 21 jewels to reduce friction. Regulation is achieved through a micrometer regulator, and the balance assembly features a monometallic balance paired with a self-compensating flat balance spring. A shock absorber is fitted to protect the movement components.
- Condition and Attribution
- The auction description assigns the manufacture to Le Locle, Switzerland. The watch, case, and movement are confirmed as signed by Ulysse Nardin. The report on the condition suggests that the case and movement are in good condition, classified as '3' and '3*' respectively. The dial is described as very good.
