- Movement Architecture and Escapement
- According to the auction cataloguing, the movement is an unsigned gilded full-plate design featuring an aperture revealing a Pouzait-type lever escapement. It is described with a large pink gold balance with spiral arms and a fan-form balance cock with a broad regulation arc. The catalogue note states that Jean-Moïse Pouzait developed a lever escapement in the late 18th century featuring a large seconds-beating balance, with slow oscillations permitting the incorporation of a dead centre seconds hand. These movement details are reported in the source text and are not visible in the provided front dial image.
- Case Construction and Exterior Features
- Constructed in silver with a stated diameter of 54 mm, the case includes a milled band and a suspension pendant with bow positioned at 12 o'clock. The cataloguing notes a stop slide located beneath the bezel at the 15-second marker. The cataloguing further describes the case back as having a decoratively engraved border and a vacant cartouche at the base. The case back is recorded as stamped "ALI incuse" and numbered 10136, though these rear features are not visible in the dial-only photograph.
