Swatch x Audemars Piguet Bioceramic Royal Pop Savonnette Lan Ba SSX03L100N

"Ba" is Mandarin for eight, and "Lan" is Mandarin for blue. The Swatch x Audemars Piguet Bioceramic Royal Pop "Lan Ba" (SSX03L100N) is one of eight pocket watches in the Royal Pop collection, each named for the word "eight" in a different language, each carrying the eight visible hexagonal screws that define the AP Royal Oak bezel. Lan Ba pairs a two-tone blue Bioceramic case with a contrasting blue octagonal bezel and crown. The Grande Tapisserie dial carries Grade A Super-LumiNova hands and hour markers with blue light emission, protected by a scratch-resistant sapphire crystal with anti-reflective coating. Eight blue hexagonal screws with a vertical satin finish complete the Royal Oak silhouette. The movement is the first-ever hand-wound Sistem51. All previous Sistem51 movements, including MoonSwatch, were automatic. This version adds a Nivachron hairspring, 90-hour power reserve, and 15 patents in a Savonnette layout with a hinged protective cover and crown at 3 o'clock. The transparent sapphire caseback showcases the movement alongside a digitally printed Pop Art design, with collaborative Swatch x AP branding on the dial, crown, and caseback. Included: an 18cm blue calfskin lanyard with light blue stitching, attached via a Bioceramic clip system. Retail: $420. Original Release Date: May 16, 2026.
