Case-Strap for the Swatch x AP Royal Pop Lan Ba

The Lan Ba — Mandarin for "blue eight" (蓝八) — is the blue Savonette in the Swatch x Audemars Piguet Royal Pop collection. A BIOCERAMIC pocket watch with no lugs and no strap, by design.

Project WristPop is our open R&D effort to give it a home on the wrist. The Savonette layout (crown at 3, small seconds at 9) needs its own dedicated case-strap design — distinct from the Lépine references. Fully reversible — no drilling, no permanent modification.
