The AP Royal Oak Selfwinding 37 mm 15450ST super clone (ref. 15450ST.OO.1256ST.01) is the all-steel 37 mm Royal Oak with a silver-toned Grande Tapisserie dial, a neutral colour that suits office and weekend alike. The dial shows the applied AP monogram over the Audemars Piguet signature at 12, white baton markers and Royal Oak hands, “Automatic” printed above 6 and a date window at 3. Case, octagonal bezel and integrated bracelet are stainless steel, the same metal as the genuine, with brushed flat surfaces and polished bevels. One honest difference: the back of our watch is closed steel, while the genuine shows its movement through a sapphire crystal.

15450ST vs 15550ST: Old and New Steel Royal Oak 37 mm

The 15450ST ran from 2012 until the anniversary update of 2022, when the 15550ST took its place. On the genuine pieces the newer model is 0.9 mm slimmer (8.9 against 9.8 mm) and swaps the 3 Hz Calibre 3120 for the 4 Hz Calibre 5900, both with 60 hours of reserve and 50 m water resistance. Its dial also changed: no monogram, no “Automatic”, just a gold signature, and the minute track moved from the flange onto the Tapisserie itself. Choose this 15450ST for the traditional dial print and a plain steel back against the skin; choose the 15550ST in ice blue if you want the current-generation look.

Does this Royal Oak 15450 replica have a display caseback?

No, it has a closed steel caseback, so the movement is not visible from the back. The genuine 15450ST uses a sapphire caseback that shows the Calibre 3120.

Is a 37 mm Royal Oak replica only for women?

No. The 37 mm case fits most wrists from about 15 to 17.5 cm, men’s or women’s, and the steel bracelet is shortened by removing links, so it can be sized for either.
