The AP Royal Oak Offshore Chronograph 26420SO replica (ref. 26420SO.OO.A002CA.01) is the 43 mm steel Offshore with a black bezel and a black Méga Tapisserie dial, from the 2021 generation that Audemars Piguet built around the in-house Calibre 4401. This super clone copies that dial: silver counters for the 30 minutes at 9 and the 12 hours at 3, small seconds at 6, red counter hands and the date in a black window at half past four. The case is stainless steel, the same metal as the genuine; the genuine bezel, crown and pushers are black ceramic.

26420SO vs 26470ST and 26400SO: Which Steel Offshore Chronograph?

The 26420 sits between two older steel models. The 42 mm 26470ST of 2014 runs on the genuine Calibre 3126/3840 with about 50 hours of reserve. The 44 mm 26400SO uses that same movement and, like this watch, sets a black ceramic bezel on a steel case, 14.1 mm thick. The 2021 Offshore chronograph 43 mm keeps the black-bezel look one size down, raises the genuine reserve to 70 hours and adds the interchangeable strap system. Choose the 26470 for the classic 42 mm shape, the 26400 for maximum wrist presence, and this Audemars Piguet Royal Oak Offshore 26420 super clone for the current design in the middle size.

How is the black 26420SO replica different from the khaki 26420SO?

Only in colour: both share the steel case, black bezel, clone 4401 and layout, but this A002CA has a black dial, silver counters and a black strap, while the A600CA pairs a smoked taupe dial with black counters.

Does the 26420SO super clone have a working flyback?

Yes. Pressing the lower pusher while the chronograph runs sends the hands to zero and restarts timing in one move, as on the genuine; function video on request.
