Record status
Individual type · partial
Period
early 20th century
This early twentieth-century marine chronometer by L. Leroy & Cie of Paris is numbered 1825 on both its silvered dial and an exterior box plaque. The movement is reported by the dealer to feature chain drive winding on the reverse, and the bowl is suspended within a brass gimbal ring fitted with a locking mechanism.
The silvered dial exhibits Roman hour numerals, blued steel hands, and a subsidiary seconds dial. It is housed in a fitted mahogany wooden transport box featuring double covers, an upper glazed inspection window, two side carrying handles, and an interior clip holding the winding key.

Design
- Visible features
- • The silvered dial displays notable surface wear, tarnish, and finish loss across the center and lower register. • A winding key is secured in a fitted brass clip inside the upper right corner of the mahogany case. • The instrument is gimbal-mounted in polished brass with an adjustable locking arm and thumbscrew knob.
- Dial and Identity Markings
- The instrument is identified by an inscription reading "L. Leroy & Cie n ° 1825 Paris" positioned on its silver dial. The dealer record notes that this designation is also reproduced on a plaque mounted on the front of the wooden box. The source describes the dial as measuring 12 cm in diameter, featuring Roman numerals for the hours, blued steel hands, and a small seconds dial. Wear and finish alteration are visible on the dial plate, where "The silvered dial displays notable surface wear, tarnish, and finish loss across the center and lower register."
- Gimbal Suspension and Wooden Casing
- The chronometer is housed within a mahogany wooden box measuring 18 cm in height, 21 cm in width, and 19.2 cm in depth. The dealer description records that the box possesses double covers, two side handles, and a first inspection cover protected by glass. For leveling and rotation, the instrument is mounted in brass. Direct observation confirms that "The instrument is gimbal-mounted in polished brass with an adjustable locking arm and thumbscrew knob," alongside "A winding key is secured in a fitted brass clip inside the upper right corner of the mahogany case."
- Reported Movement and Technical Limitations
- The listing reports a "Chain movement in perfect working order" with "Winding on the back" and attributes manufacture to the early twentieth century. These mechanical and operational claims reflect dealer assertions rather than verified testing. Neither the internal movement plates, the escapement type, nor the balance assembly are visible in the provided imagery. Consequently, internal mechanical configuration and condition cannot be independently confirmed from this documentation alone.
