Object description

Dial Configuration and Material

The component is a specialized dial designed for Gerald Genta wristwatches featuring a full calendar and moonphase display. It is composed of onyx, which provides a dark, minimal aesthetic contrasted by the functional sub-dials. The layout includes three circular registers arranged for the display of days of the week, calendar dates, and a 24-hour indicator, arranged around the central moonphase aperture.

The surface of the onyx exhibits a noted patina, which the source describes as a characteristic feature that accumulated over time. The indices are marked with luminous material, reported to be in suitable condition despite the age of the component. The branding is applied in a distinct typeface above the moonphase opening.
