The timepiece is constructed from 18K white gold and measures 34mm in diameter. The dial is composed of mother-of-pearl and features diamond-set hour markers, contributing to its aesthetic appearance. The watch is equipped with a distinct double-row diamond-set bezel.

The perpetual calendar functions are displayed across three subsidiary dials, while a moon phase indicator is located at the 6 o'clock position.
