Green dial chronographs were inevitable after what happened in 2021 — every brand chased the color, but AP actually made it work. The 26240ST in green Grande Tapisserie reads forest-dark indoors and opens up to an almost olive tone in natural light. This replica royal oak 26240ST green pairs that dial with the updated 41mm chronograph case and Cal. 4401 flyback, which is the movement the old 26331 should have had from the start.
What Changed from the 26331 to the 26240
The 26240 generation rewrote the Royal Oak chronograph properly. Gone is the Renaud & Papi-sourced movement; the Cal. 4401 is fully in-house with a column wheel, vertical clutch, and flyback function. That last bit matters more than people realize — you can reset and restart the chronograph with a single pusher press instead of the usual stop-reset-start sequence.
Case proportions changed too. The subdials are vertically stacked now (6 and 12 o’clock) instead of the old 3-9 layout, which gives the dial more breathing room. The pushers integrate flush with the case rather than protruding, so nothing catches on sleeve cuffs. At 12.4mm thick, it wears noticeably chunkier than the time-only 15400, but for a flyback chronograph that’s genuinely thin.
The blue dial 26240ST runs the same case and movement if you want the signature Royal Oak color instead.
Green on Steel and How It Wears
AP’s green isn’t the bright Hulk-style green that Rolex made famous. It’s deeper, more muted, closer to British racing green with a warm undertone. The Grande Tapisserie texture means you never see a flat plane of color — every tiny facet catches light at its own angle, so the dial looks alive rather than painted.
On steel, the green sits in an interesting space. It’s clearly not a conservative choice, but it also doesn’t scream for attention the way a skeleton or iced-out piece does. The applied markers and hands are white gold toned, which provides enough contrast for legibility without the yellow warmth you’d get from rose gold markers. The chronograph seconds hand adds a single accent line sweeping the outer track.
Worth noting the bracelet on the 26240 uses a different link shape than the 15400 series — slightly wider individual links with a more gradual taper. Check our return policy if you want to compare in hand before committing. This replica royal oak 26240ST is the real deal.
