L. Leroy & Cie 8-Day Going Marine Table-Clock

Partially verified

This L. Leroy & Cie marine-style table clock features an 8-day going movement housed within a lacquered brass chronometer-style barrel. The clock is mounted upon a mahogany base designed to resemble a ship's porthole, with a hinged support for the barrel that also accommodates the winding key. The silver-colored dial displays suspended luminescent Arabic numerals and blued steel skeleton hands, with a subsidiary seconds dial positioned at 6 o'clock and a sector for 8-day power reserve indication at 12 o'clock. The movement, a gilded brass 24''' // 36''' caliber, incorporates a platform with a straight-line lever escapement, a monometallic screw-balance, and a self-compensating flat hairspring regulated by a polished steel index-regulator. The piece is signed on the dial, case, and movement and includes a brass winding key.

Object description

Case and Dial Design

The table clock is presented in a marine-themed aesthetic, characterized by a mahogany base that the source describes as reminiscent of a ship’s porthole. The primary housing for the clock is a lacquered brass chronometer barrel, which is mounted on a hinged support of the same material. This housing arrangement provides structural depth and integrates the functionality of housing the winding key within the mounting assembly.

The dial is executed in a silver color, featuring suspended luminescent Arabic numerals for the hours. Time is indicated by blued steel skeleton hands. Complications on the dial include a subsidiary seconds register located at the 6 o'clock position and a power reserve sector situated at 12 o'clock, which displays the status of the 8-day mainspring. The assembly is signed on the dial, case, and movement.

  • “Silver colour dial with suspended luminescent Arabic numbers; blued steel skeleton hands.”
  • “Signature dial, case and movement”

Movement and Escapement

The movement is a gilded brass caliber measuring 24''' // 36''', designed for an 8-day going period. It utilizes a going barrel to provide power to the mechanism. The oscillator comprises a monometallic screw-balance paired with a self-compensating flat hairspring, consistent with its era of manufacture.

Regulation is achieved via a polished steel index-regulator mounted on the balance bridge. The escapement is a straight-line lever type, mounted on a platform that sits within the brass barrel assembly, allowing for the clock's characteristic marine chronometer configuration.
