Audemars Piguet Royal Oak Chronograph 26331ST.OO.1220ST.01 41mm Blue Grande Tapisserie

The Royal Oak Chronograph 26331ST.OO.1220ST.01 makes its point through the contrast between blue Grande Tapisserie and silver chronograph registers. The counters sit clearly inside the blue field, which gives the dial a more technical, graphic look than a monochrome Royal Oak. At 41mm, the steel case and integrated bracelet give that dial enough space to read as a full sports chronograph rather than a compact variation.

The blue surface retains depth around the registers, while the silver counters give the eye a quick route across the elapsed-time display. That balance is the appeal: the watch carries visible function, but it still has the clean octagonal bezel and bracelet line that make the Royal Oak recognisable from across a room. It suits a collector who wants a chronograph to look like a deliberate part of the rotation, not a busier version of a three-hand watch.

The silver-and-blue 26315ST 38mm chronograph uses a similar colour idea on a more compact wrist scale. This 26331ST gives the registers more breathing room and makes the steel bracelet feel broader. The choice is straightforward: select the 38mm model for restraint, or this 41mm version when the dial and case should have more immediate presence.

APS Factory lists a Calibre 2385 clone for the configuration. The useful distinction is the traditional chronograph layout, which keeps the silver counters, running seconds and central timing hand integrated into a blue dial that remains readable rather than overcrowded.
