Build Your Own Sport Rubber Strap & Case — AP × Swatch Royal Pop (Crown at 12)

Build your own Royal Pop rubber strap. Choose your favorite color and get a case-and-strap set engineered to click directly onto your Royal Pop's bioceramic coupler — no drilling, no glue, no permanent changes, converting it from a pocket watch into a wristwatch.

The soft-touch rubber strap is built for daily wear: flexible, sweat- and sunscreen-resistant, and easy to clean. Designed specifically for the crown-at-12 (Lépine) references. Every build is made to order — remove it anytime to return your Royal Pop to its original lanyard configuration.
