Among these extraordinary watches is the stainless steel Royal Oak Openworked Double Balance Wheel with a salmon dial (Reference 15407ST).

The collection also includes the strikingly discreet black ceramic version (Reference 15416CE). Crafted entirely from ceramic, this watch presents an understated yet distinguished appearance. Ceramic, known for its resilience and unique reflective qualities, provides the piece with a distinctively refined finish. The incorporation of golden accents on both the bridges and the double balance wheel highlights the technical precision and complexity that Audemars Piguet's craftsmen achieve. This subtle interplay of gold and black ceramic elevates the watch's overall visual impression, blending a restrained presence with technical mastery.

Completing the trio is the exceedingly rare white ceramic model (Reference 15416CB), produced in an extremely limited run of just thirty pieces. This variation stands apart not solely due to its rarity, but through the exceptional use of aventurine in the dial's surrounding ring. Aventurine, prized for its distinctive, starry appearance, introduces an element of subtle exclusivity. Audemars Piguet's choice to integrate such uncommon materials underscores their dedication to creating pieces that represent both technical innovation and understated luxury.

Each of these Openworked Double Balance Wheel watches employs calibre 3132, distinguished by its dual-balance wheel design. This advanced mechanical arrangement consists of two balance wheels placed on a shared axis at differing heights, stabilized by independent bridges and hairsprings. This configuration enhances accuracy, stability, and shock resistance, attributes particularly valuable for a watch intended to be worn daily.
The complex production process required for crafting ceramic cases further emphasizes the exclusivity of these timepieces. Ceramic demands precise conditions, including heating to temperatures exceeding 2,000 degrees Celsius and meticulous shaping using specialized diamond-tipped instruments. The result of this rigorous method is a material that boasts superior hardness compared to traditional steel, combined with a sleek, polished appearance.
