Model Kristina Ozimkova spotted wearing a Audemars Piguet

Kristina Ozimkova, the Czech model and social media personality known for her close relationship with the luxury watch world, was recently spotted wearing the Audemars Piguet Royal Oak Concept Frosted Gold Flying Tourbillon, reference 26630BC — a watch that sits at the very apex of the Le Brassus manufacture's creative output.

The Royal Oak Concept line was launched in 2002 as a platform explicitly free from conservative restraint, designed to push AP's technical and aesthetic boundaries beyond what the classic Royal Oak architecture would allow. The ref. 26630BC houses the calibre 2966, a manual-winding flying tourbillon movement with a 72-hour power reserve. The tourbillon cage — rotating once per minute — is skeletonized and architecturally echoes the multi-level dial beneath it, creating a visual dialogue between complication and surface. The dial itself features a gradient sunray finish developed across several depth layers, giving it a three-dimensional quality that photography struggles to capture accurately.

The defining surface treatment, however, is the frosted gold finish. Carolina Bucci, the Florence-based jeweler, revived a Renaissance-era burnishing technique in which a diamond-tipped tool hammers thousands of microscopic indentations into the gold surface. The result is a soft, luminous sparkle that differs entirely from both brushed and polished finishing — warmer, more tactile, and extraordinarily labor-intensive. On the 41mm white gold case of the 26630BC, the effect is simultaneously bold and restrained.

Ozimkova has cultivated a visible appreciation for serious horology, and the choice of the Royal Oak Concept Frosted Gold Flying Tourbillon signals more than accessory awareness — it reflects familiarity with a watch that demands a committed collector's eye. The piece is not a mainstream Royal Oak; it targets a buyer who understands the Concept line's distinct identity within the AP catalog.

On the market, the ref. 26630BC occupies rarefied territory. With a retail price in the range of $340,000, it was produced in very limited numbers, and secondary market availability is scarce. Grey market values have held firm given the combination of a complex in-house movement, a proprietary surface technique, and AP's sustained brand momentum. This is not a watch that depreciates quietly.
