Audemars Piguet Royal Oak 15510ST.OO.1320ST.06
This self-winding Royal Oak has a 41 mm steel case and a blue Grande Tapisserie dial. Its bezel and bracelet define its visual identity, but the full reference is the most precise way to distinguish it from other versions.
What does the dial name mean?
Grande Tapisserie names the dial pattern; this version’s colour is called Bleu Nuit, Nuage 50. These names describe design details, not extra functions.
What does the caseback reveal?
The sapphire caseback allows a view of the movement. Movement details differ from dial details even when both appear in one image.
Why is 15510ST not enough?
The final part of the reference identifies the version. Do not assign another version’s colour or specifications based only on the start of the number.
