What does Calibre 2385 mean in this watch?
Calibre 2385 connects the QEII edition to the broader history of the Royal Oak Chronograph. Audemars Piguet dates the first Royal Oak Chronograph to 1997 and says it introduced the model alongside the newly developed selfwinding chronograph movement, Calibre 2385. The brand lists the calibre’s thickness as 5.5 mm and credits its development to collaboration with movement-blank manufacturer Frédéric Piguet. Audemars Piguet’s “Measuring Time Interval” history.
AP’s design history also identifies a 39 mm Royal Oak chronograph among the complications introduced for the collection’s 25th anniversary in 1997. That historical 39 mm figure describes the anniversary-era model, not the 41 mm QEII Cup edition. Audemars Piguet’s design history.

How is the QEII Royal Oak different from the QEII Offshore?
“QEII” alone does not identify a single watch. The 2018 QEII Cup model is a Royal Oak Offshore Chronograph, reference 26474TI.OO.1000TI.01, rather than the 2015 standard Royal Oak Chronograph. Phillips catalogued the 2018 watch as a 42 mm titanium Offshore with Calibre 3126/3840, also limited to 200 pieces. Its case size and movement should not be attributed to reference 26327TI.OO.D004CA.01.
| Edition | Reference | Case and material | Movement | Reported edition size |
|---|---|---|---|---|
| Royal Oak Chronograph QEII Cup, 2015 | 26327TI.OO.D004CA.01 | 41 mm titanium | Selfwinding Calibre 2385 | 200 pieces |
| Royal Oak Offshore Chronograph QEII Cup, 2018 | 26474TI.OO.1000TI.01 | 42 mm titanium | Calibre 3126/3840 | 200 pieces |
