Both front and back are fitted with glareproof sapphire crystals, and water resistance is rated at 50 meters. The integrated stainless steel bracelet is secured with an AP folding clasp. The dial is light blue with the signature Grande Tapisserie pattern. It features tone-on-tone subsidiary dials for the perpetual calendar indications, complemented by white gold applied hour markers and hands with luminescent coating, and a silvery-grey inner bezel.

It operates at a frequency of 28,800 vph (4 Hz) and has a power reserve of 55 hours.
