The round 41mm case is crafted from black ceramic and fitted with a sapphire dial that reveals the movement within, framed by pink gold and black hour-markers, pink gold hands, and a black lacquered inner bezel. Water resistance is rated to 20 metres. The strap is black rubber-coated with pink gold colour stitching, fastening by way of an 18-carat pink gold AP folding clasp.
Powering the watch is a hand-wound calibre measuring 29.9mm in diameter and 5.9mm thick, comprising 498 parts and 53 jewels. It beats at 3 Hz (21,600 vph) and delivers a 48-hour power reserve. Complications include Grande Sonnerie Supersonnerie, Petite Sonnerie, and Minute Repeater alongside hours, minutes, and small seconds.
