Introducing AP Launches the First 38mm Perpetual Calendar Models

As one of the biggest names in Swiss watchmaking, Audemars Piguet is renowned for creating some of the industry’s most complicated and finely crafted timepieces. The brand has consistently pushed boundaries, with its releases often stealing the spotlight. Now, in its 150th anniversary year, Audemars Piguet is unveiling the Royal Oak and Code 11.59 Perpetual Calendar in a newly downsized and more wearable 38mm case for the first time.

Traditionally housed in 41mm cases, this more compact interpretation makes one of watchmaking’s most poetic complications accessible to a wider range of wrists.

The Code 11.59 Selfwinding Perpetual Calendar comes in 18K pink gold with a diameter of 38mm and a thickness of 9.9mm, while the Royal Oak Selfwinding Perpetual Calendar measures 38mm × 9.4mm and is offered in stainless steel or 18K pink gold. All three models feature sapphire casebacks that reveal the movement. The Code 11.59 is water-resistant to 100 meters, while the Royal Oak is rated at 50 meters.

The Code 11.59 showcases a green guilloché dial, crafted by Swiss master artisan Yann Von Kaenel, with embossed concentric motifs adding depth. The Royal Oak is offered in two variations: a light blue “Grande Tapisserie” dial with snailed counters in steel, and a beige “Grande Tapisserie” dial paired with a moon phase at 6 o’clock. Across all models, the calendar indications, day, date, month, leap year, and moon phase, are arranged with symmetry, while the moon phase itself draws inspiration from NASA imagery.

These watches debut Audemars Piguet’s new selfwinding calibres 7136 and 7138, both measuring just 4.1mm thick and delivering a 55-hour power reserve. Each movement is protected by five patents and incorporates an all-in-the-crown correction system that eliminates the need for case-side correctors, allowing all functions to be adjusted directly via the crown which we covered in detail here.

The Code 11.59 is paired with a green textured rubber strap lined with calfskin, secured by a pink gold folding clasp. The Royal Oak models feature matching bracelets in steel or pink gold with folding clasps. Each of the three perpetual calendar references is limited to 150 pieces, priced at $110,900 (≈ AED 407,300) for the steel model, and $150,000 (≈ AED 550,900) for the pink gold Royal Oak.
