Object description

Case and Dial Design

The timepiece features a 40mm case constructed from 18-karat white gold. Notable design elements include a polished, concave bezel and lugs that are hollowed. The dial follows a blue sunburst finish and is organized according to a sector design. The arrangement provides apertures for the day, date, and month, which are positioned to maximize readability.

The indices are applied baton-style markers, which are paired with dauphine hands. The dial also houses a sub-dial that displays the moonphase and a 24-hour indication. A sapphire crystal is utilized for the front display, and another provides visibility to the movement at the rear of the case.

Movement and Technical Specifications

The watch is driven by the caliber 324 S QA LU 24HR, a self-winding automatic movement. This mechanical system is specifically designed to manage the annual calendar complication, which includes the tracking of the day, date, and month, requiring adjustment only once a year.

In addition to the calendar functions, the movement incorporates a moonphase display. The engineering of the caliber is intended to maintain precision for the calendar displays while providing a stable power reserve for the daily timekeeping functions.
