The AP Royal Oak Selfwinding 37 mm 15550ST super clone (ref. 15550ST.OO.1356ST.08) belongs to the current 37 mm generation that Audemars Piguet introduced in 2022, the Royal Oak’s 50th year, here with the pale “ice blue” Grande Tapisserie dial. As on the genuine 15550, the dial is signed only “Audemars Piguet” at 12, without the applied AP monogram or the word “Automatic” that the older 15450 carries. White baton markers, Royal Oak hands and a date at 3 complete the face. Like the genuine ST reference, our watch is steel throughout, from the bezel with its eight hexagonal screws to the bracelet clasp.

15550 vs 15450: What Changed in the 37 mm Royal Oak

Three changes separate the 15550 from the 15450 it replaced. The genuine case went down from 9.8 to 8.9 mm in height. The Calibre 5900 beats at 4 Hz where the Calibre 3120 ran at 3 Hz, and both are rated for 60 hours. And the dial signature became a single 24K gold “Audemars Piguet” grown onto the dial, with the minute scale printed on the Tapisserie rather than on the flange. Pick a 15450 from our stock in silver, blue, black or grey if you like the monogram-and-“Automatic” layout; pick this 15550ST for the latest generation in a lighter colour.

What does “ice blue” mean on the Royal Oak 15550 replica?

It is the pale, sky-like blue of the 15550ST.OO.1356ST.08 dial, far lighter than the dark “Bleu Nuit, Nuage 50” that Gérald Genta chose for the 1972 Royal Oak. Under the raised Tapisserie squares it reads as a soft, almost pastel blue.

Why is there no AP logo on the 15550 super clone dial?

Because the genuine 15550 has none either: in 2022 Audemars Piguet dropped the applied AP monogram and the “Automatic” text from the 37 mm Royal Oak and kept only the signature at 12, so the clean dial is correct for this reference.
