The entire circumference of the caseband is decorated with the maison’s hobnail guilloché pattern. A sapphire crystal case back is fitted.

The display includes an instantaneous day indication in an aperture, an instantaneous date by hand, a power-reserve indicator at 12 o’clock, and a small seconds display at 6 o’clock. Powering the watch is the manually wound calibre 31-505 8J PS IRM CI J. The movement measures 32 mm in diameter and 5.05 mm in thickness, comprises 256 components and 28 jewels, and operates at a frequency of 28,800 semi-oscillations per hour (4 Hz).

The watch is delivered on a blue calfskin strap with fabric pattern and cream stitching, secured by a patented triple-blade white-gold fold-over clasp.
