The AP Royal Oak Selfwinding 37 mm 15450BA replica (ref. 15450BA.OO.1256BA.01) is the yellow gold-tone version of the mid-size Royal Oak, paired with a silver-white Grande Tapisserie dial. The applied baton markers and all three hands are gold-coloured, with the AP monogram above the signature at 12, “Automatic” in the lower half and the date at 3. On our watch the case, eight-screw bezel and integrated bracelet are stainless steel with a yellow gold-tone finish; Audemars Piguet makes the genuine 15450BA in 18K yellow gold.

15450BA Yellow Gold Tone vs 15450ST Steel and the Newer 15550

The 15450BA and the steel 15450ST share one case: 37 mm across, 9.8 mm high on the genuine, with the Calibre 3120 inside. So the choice is colour: gold tone looks warmer and dressier, all-steel is the quieter daily option. Audemars Piguet launched the 15450 in 2012 and replaced it in 2022 with the 15550, which uses the Calibre 5900 at 4 Hz instead of 3 Hz and removes both the AP monogram and the “Automatic” line from the dial. Pick this 15450BA if you like the older two-line signature in a gold colour; pick the 15550 if you prefer the plainer, newer dial.

Is the yellow gold on this Royal Oak 37 mm replica real gold?

No, it is a yellow gold-tone finish on stainless steel. Steel is roughly half as dense as 18K gold, so the replica is also lighter on the wrist than the genuine.

Will a 37 mm Royal Oak super clone look too small on a man’s wrist?

Not on a wrist up to about 17 cm: the wide octagonal bezel and the integrated bracelet that flows straight out of the case make the 37 mm Royal Oak wear larger than the number suggests. Above roughly 18 cm, a 41 mm Royal Oak is the safer fit.
