Four Core Highlights

• 【Case】The classic 41mm case perfectly balances a commanding presence with a comfortable fit. The iconic octagonal bezel is secured by eight polished screws, featuring meticulously brushed facets and rounded corners that feel smooth to the touch. Complete with an anti-reflective sapphire crystal and a screw-locked crown, it exudes pure luxury within a rugged architecture.
• 【Dial】The "Grande Tapisserie" dial features 0.1mm-deep diamond-patterned grooves with 45-degree polished facets. A nano-PVD coating imparts a deep, lustrous finish to the dial, concealing a sharp refinement beneath its understated elegance.
• 【Bracelet】The all-solid bracelet, crafted from matching material, showcases delicate brushing on the links and exquisite polishing on the edges, ensuring every seamless articulation fits perfectly. Secured by a folding clasp engraved with the AP logo, it opens and closes cleanly, offering a stable and comfortable wear. The overall lines are bold and fluid, integrating seamlessly with the case.
• 【Free-Sprung Calibre 4302】Powered by the all-new Cal.4302 automatic movement, it features a free-sprung balance wheel with regulating weights. By eliminating the traditional regulator mechanism and tuning the rate directly via the balance weights, shock resistance is enhanced by 40%, and timing deviation approaches zero. The bidirectional self-winding efficiency is increased by 15%. A skeletonized gold oscillating weight is paired with Côtes de Genève and perlage finishing, visible through an expansive exhibition caseback that fully displays its mechanical beauty. Beating at 28,800 vph, it remains accurate and stable through the test of time, serving as a flawless manifestation of Haute Horlogerie.
