Launched in 2026, the Audemars Piguet × Swatch Royal Pop Lan Ba SSX03L100N stands out as one of two Savonnette-style pieces within the Royal Pop series. This model features the crown positioned at 3 o'clock, distinct from the six Lépine-style references, and incorporates a small seconds subdial at the 6 o'clock mark. Crafted from blue Bioceramic, it showcases a light blue crown and an octagonal bezel, with overall dimensions of 40.0 mm in width without the clip, expanding to 44.2 × 53.2 mm when attached to the holder clip, and a thickness of 8.4 mm. The design includes a removable clip, usable with a blue calfskin lanyard that has light blue contrast stitching. The striking blue dial features a tapestry texture and the small seconds subdial at 6 o'clock creates a more segmented reading compared to models without this complication, while proudly displaying both the AP × Swatch collaboration logo and the Royal Pop logo. Hour markers and hands are illuminated with Grade A Super-LumiNova emitting a blue hue. The vertically satin-finished light blue bezel is adorned with eight blue hexagonal Bioceramic screws. Additionally, the watch is protected by sapphire crystals on both sides, treated with an anti-reflective coating, including a transparent case back that allows for a glimpse of the hand-wound SISTEM51 movement with a small seconds complication.
