Royal Pop Wrist Strap & Case — For Lan Ba (Savonnette, Crown at 3)

The Royal Pop that was always meant for a strap. The Audemars Piguet × Swatch Royal Pop “Lan Ba” is the Chinese-named Savonnette reference — one of only two in the collection — with the crown at 3 o’clock and a small seconds sub-dial at 6 o’clock. It is the closest thing in the collection to a wristwatch dial. The Helvetus strap and case set finishes the job. The strap and case system the Royal Pop was missing The Audemars Piguet × Swatch Royal Pop was designed as a Bioceramic pocket watch — carried on a calfskin lanyard or clipped to a bag. Swatch did not include a wrist strap. We did. The Helvetus Royal Pop strap and case set converts the pocket watch into a fully wearable wristwatch in seconds: pop your Royal Pop out of its original chassis, click it into our precision-fit case, attach the strap, and you are wearing the Royal Oak silhouette on your wrist for the first time. Built by the Royal Oak strap specialists Helvetus has been engineering aftermarket straps for the Audemars Piguet Royal Oak family for years — Royal Oak 39, Royal Oak 41, Offshore 42, Offshore 44, and the Offshore Diver. No other strap brand offers a deeper Royal Oak compatible range. The Royal Pop strap and case set is a direct extension of that work, engineered around the exact 40 mm octagonal Bioceramic case head (8.4 mm thick) so the strap sits flush against the case, the case sits flush against the watch, and the exhibition caseback — the decorated hand-wound SISTEM51 movement — stays fully on show. Made for Lan Ba Color-matched to the Lan Ba (Ref. SSX03L100N), this case is finished to sit cleanly against the baby-blue and deep-blue palette. The FKM rubber strap is available in matched deep blue, light blue, and neutral options. Because the Lan Ba is a Savonnette reference with the crown already at 3 o’clock and small seconds at 6 o’clock, this set keeps the traditional wristwatch dial orientation — the result is the most “authentic Royal Oak” silhouette you can build out of the Royal Pop collection. The strap — premium FKM rubber, stainless steel buckle The Helvetus Royal Pop strap is cut from premium FKM rubber — the same compound we use across our Rolex, Audemars Piguet, and Patek Philippe strap range. FKM is the gold standard for luxury watch straps: it does not discolor, does not crack, repels water and sweat, and stays comfortable from the first wear. The strap terminates in a brushed stainless steel buckle, available in your choice of finish, and is engineered so the lug-end geometry mates cleanly with the Royal Pop case — no gap between strap and case, no awkward break in the line, no compromise on the Royal Oak silhouette. Non-destructive, fully reversible No drilling, no modification, no permanent change to the watch. The case clicks around the original Bioceramic case head and the strap clips into the case — both can be removed in seconds, returning your Royal Pop to its original pocket-watch configuration whenever you want. Build the Royal Pop you actually want to wear Strap color — premium FKM rubber in multiple colors, matched or contrasted to the Lan Ba palette- Case color — multiple colorways available for the Lan Ba reference- Buckle color — choose your stainless steel finish- Fully interchangeable — swap straps, swap cases, swap buckles.
