Object description

Dial and Complications

The dial is rendered in an opaline silver tone, featuring blackened gold applied indexes and matching dauphine hands. It provides a comprehensive calendar display that includes the current day of the week and the date. A primary feature is the peripheral monthly track, which indicates the current week number. The typography on the dial is noted for being derived from early concept drawings, resulting in a distinct visual style where letterforms are not identical.

The arrangement of the calendar information is designed to track weekly cycles, a functionality identified in the source as being suited for international business use. The inner track facilitates the display of the day and month, while the outer scale correlates the time of year with the specific week of the calendar year.
