Design language
Both watches carry the octagonal bezel, exposed screws and ‘tapisserie’ dials. The **16202** is extra‑thin at about **8.1 mm** and reads pure Gerald Genta minimalism. The **15510** wears bolder with a 41 mm case and slightly thicker profile, giving more presence while preserving the Royal Oak’s DNA.
Movements & thickness
The **16202** introduced the modern **calibre 7121**, replacing the long‑running 2121 and bringing improved winding and stability in a compact package. The **15510** uses a current‑generation in‑house automatic with date and exhibition back. If you want the thinnest classic silhouette, the 16202 is the one; if you prefer a more contemporary stance, 15510 feels right.
Bracelet & finishing
AP’s bracelet finishing is a reason to buy on its own: brushed planes with razor‑sharp polished bevels that catch light. On‑wrist, the 39 mm ‘Jumbo’ drapes like jewellery; the 41 mm brings more visual punch and arguably better legibility for some wrists.
