This replica Royal-Oak 02 brings the Royal Oak Chronograph into 18K white gold territory with the 26240BC.GG.1324BC.02 reference. The “BC” material code stands for “Blanc Ceramic” finish on white gold, giving the case and bracelet a frosted, textured surface that AP pioneered through its collaboration with Florentine jewelry artist Carolina Bucci. At 41mm, this is a full-size chronograph with three subdials, and the frosted white gold finish transforms what would otherwise be a polished precious-metal sports watch into something visually distinct. The frosted technique hammers the gold surface with a diamond-tipped tool, creating thousands of tiny indentations that scatter light in every direction.

The frosted gold surface diffuses reflections rather than producing sharp mirror-like glints. Under direct sunlight the effect is unmistakable, creating a glowing, almost fabric-like texture across every visible surface.

Caliber Breakdown

Audemars Piguet equips the 26240 chronograph series with an integrated automatic movement that drives the central chronograph seconds hand and the three subdials for running seconds, 30-minute counter, and 12-hour counter. The column-wheel design provides a crisp push-feel through the chronograph pushers, and the flyback function allows instant reset-and-restart without stopping the chronograph first. Integrated chronograph movements are thinner than modular ones because the chronograph module is built into the base caliber rather than stacked on top. Explore the full Royal Oak collection to see how this chronograph relates to the time-only and perpetual calendar references. For a different precious-metal approach, the 15500ST blue dial on rubber strips everything back to steel and automatic simplicity.

How It Compares

Within the 26240 family, the frosted white gold BC version stands apart from the standard polished or brushed finishes. The frosted treatment adds a dimension of texture that photographs struggle to capture accurately. It needs to be seen under changing light to appreciate fully. White gold also means the watch reads as silver-toned rather than warm, giving it a cooler personality than the rose gold 26239OR chronograph. At 41mm it wears identically in terms of dimensions, so the decision comes down to finish and metal color. This replica Royal-Oak 02 in frosted white gold is the statement piece of the chronograph sub-family, for those who want AP engineering wrapped in unconventional surface treatment.
