- The silvered dial is marked with upright Arabic numerals executed in champlevé. The dial layout includes an outer ring for minute tracking. Subsidiary indications are provided via a sunk seconds dial located at the 6 o'clock position and an up/down winding indicator positioned at 12 o'clock. The time is displayed using blued steel hands in a spade configuration. The auction description notes that the dial currently exhibits signs of oxidation.

- Case and Exterior
- The timepiece is contained within a two-body mahogany box designed for maritime use. The box features brass hardware, including corner reinforcements and a hinge system. The watch itself is set within a gimbal mechanism, which allows the instrument to remain level despite the motion of a vessel. A locking mechanism is provided for the gimbals, consisting of a swiveling arm that presses against the base of the cylinder. The watch case is constructed from brass and incorporates a threaded, glazed bezel. The overall dimensions of the box are 10 cm in height by 14.5 cm in width and depth.
- Movement and Escapement
- The internal mechanism is a 52 mm (23-ligne) half-plate movement with a rhodium-plated finish. The gear train consists of five wheels and the movement contains 19 jewels. A straight-line lever escapement provides the pulse of the watch, regulated by a cut bimetallic compensation balance and a Breguet balance spring. A notable feature of this movement is the inclusion of a patented micrometric cam-type regulator for precision adjustment. The auction documentation states that the movement currently requires an overhaul.
