Object description

Physical Description

The pocket watch is housed in a nickel-plated brass case, which encompasses the movement and dial assembly. The case diameter is 45.0 mm, and the item has a total recorded weight of 0.08 kg. The primary materials identified by the museum include a mixture of copper, brass, and bronze alloys.

The dial is finished in white enamel, featuring Roman numeral hour markers. A smaller subsidiary dial, located at the six o'clock position, provides a dedicated display for seconds. The overall design follows the traditional configuration for a key-wound cylinder movement pocket watch.

Movement and Markings

The timepiece is identified as a cylinder escapement watch. The case bears a specific inscription detailing the escapement type and the jewel count. The text reads 'Echappement Cylindre. Huit Rubis', which translates to an eight-jewel cylinder escapement movement.

Operation of the watch is achieved through key winding. Documentation confirms that the essential winding key is currently missing from the object's inventory, preventing the operation of the gear train or the mainspring mechanism.
