Object description

Case and Dial Design

The clock is housed in a case constructed from bronze or brass, which has been finished with manual polishing. The design incorporates bevelled glass panels on the sides and top, a feature intended to permit visibility into the clock's internal mechanisms.

The primary white enamel dial is configured with Roman numerals to indicate the hours and minutes. Positioned in the lower section of the dial is an independent sub-dial designated for alarm settings, allowing the user to manage the integrated chime function.
