Launched in 2026, the Audemars Piguet × Swatch Royal Pop Otto Rosso SSX03R100N is a notable addition to the Royal Pop lineup, showcasing a Lépine-style design. This model features a vibrant pink Bioceramic casing adorned with a striking cherry red octagonal bezel and crown, creating a harmonious color scheme among the eight new pieces. With dimensions of 40.0 mm excluding the clip and 44.2 × 53.2 mm when attached, it measures 8.4 mm in thickness, maintaining a traditional pocket-watch appearance while the removable clip enables versatile wear with the included calfskin lanyard or a small stand.

Crafted from Bioceramic — a blend of ceramic powder and sustainable materials from castor oil — the case, crown, hexagonal screws, and clip reflect its unique material choice. The pink dial presents a tapisserie pattern featuring the AP × Swatch collaboration logo alongside the Royal Pop logo, and follows a streamlined layout showing only the hours and minutes, with the crown positioned at 12 o'clock. Completing its design, the hands and hour markers are treated with Grade A Super-LumiNova to emit blue light. The vertically satin-finished cherry red bezel showcases eight pink hexagonal Bioceramic screws, while the pocket-watch format also nods to Swatch's POP style from the 1980s. Finally, the watch is protected by sapphire crystals on both sides with anti-reflective coating, with the case back revealing a glimpse of the manually wound SISTEM51 movement.
