ZF | Royal Oak Chronograph 26240CE — Black Ceramic, Pink Accents, No Regulator

Black ceramic is the material that punishes laziness. You can’t polish away a soft edge later, and every bevel is either right or permanently wrong. That makes the genuine 26240CE one of the hardest integrated chronographs to copy: a 41 mm case, bezel and bracelet all in black ceramic, a black Grande Tapisserie dial, and pink gold hands and indices that glow like embers against all that black. Underneath sits the in-house 4401, a column-wheel flyback chronograph with a 70-hour reserve, behind a sapphire caseback. Retail is well into six figures if you can find one, and you mostly can’t.

ZF now appears to be taking it on. A pre-order announcement doing the rounds today promises a full black ceramic finish and a free-sprung balance. The factory flyer goes further. It claims a new 4401-type calibre with no regulator, a one-push flyback reset and smooth, snag-free chronograph action. It also highlights the large Grande Tapisserie pattern, which should look subdued in dim light and sharply three-dimensional under strong light.

Some of that rests on recent history. ZF reportedly updated its steel and gold versions of this chronograph earlier in the summer with a free-sprung 4401-type movement, and early buyers said they could see separate weights on the balance wheel. Whether the ceramic version gets the same movement is the obvious question, and so far the evidence is a flyer and a sentence.

So what should early buyers check? Start with the case. The brushed surfaces should be fine and even, and the bevels should be crisp and polished without any rounding. Ceramic should look dense, not plasticky, and the case, bezel and bracelet should be the same shade of black. Then look at the pink-gold tone of the hands and indices, which should be warm without turning orange. Finally, ask for a clear photo of the balance. A true free-sprung balance has separate weights on the rim and no regulator arm. Weights alone, sitting next to a regulator, are just decoration.

If it all holds together, this could be the strongest black-ceramic chronograph in the replica world. If it doesn’t, at least black hides fingerprints.
