Strap for Royal Pop Otto Rosso

Strap kit only — the watch is not included.

Across the AP x Swatch Royal Pop collection, every model spells out the same number — eight, for the eight screws of the Royal Oak — in a different language and a different colour. The Otto Rosso is the Italian one: "eight in red," and the most extroverted of the family. Like every Royal Pop, though, it arrives on nothing but a calfskin lanyard, so this pocket-watch icon rarely leaves the drawer. This Royal Pop strap & case set — part of WatchCollab's Audemars Piguet x Swatch straps — fixes that: it turns your Otto Rosso into a wristwatch in seconds, with no modification to the watch and no toning-down of that unapologetic red.

Built around the exact case geometry of the Royal Pop, the set pairs a colour-matched red FKM band with a precision adapter case, so your Audemars Piguet x Swatch Royal Pop Otto Rosso finally moves from pocket to wrist — and back whenever you like.

The Royal Pop Otto Rosso: eight, in red

The Otto Rosso keeps every Royal Oak cue — the octagonal bezel, the eight hexagonal screws, the Petite Tapisserie dial — and saturates them in a bold, confident red, driven by a hand-wound SISTEM51 movement with over 90 hours of reserve. It's a watch made to be seen, which is exactly why it shouldn't live in a box. Our strap and case set is built to keep it on your wrist, every day.

From pocket watch to everyday wristwatch

Out of the box the Otto Rosso only offers lanyard wear. The WatchCollab set closes that gap with two parts that work together: a precision adapter case that cradles the watch head snugly and rattle-free, and a premium red rubber Royal Pop strap ready to wear the moment it arrives. Fitting takes seconds and is fully reversible — the watch returns to its original lanyard configuration just as easily.

Built for the Royal Pop's exact geometry

This is no generic band. Case and strap are engineered specifically for the Royal Pop and work with both layouts of the collection — crown at 3 and crown at 12. The adapter frames the watch so the octagonal bezel, the eight screws and the red Petite Tapisserie dial stay on full display, while protecting the case edges from knocks.

Premium materials, all-day comfort

The strap is high-grade FKM rubber — supple from the first wear, sweat- and water-resistant, UV-stable so the red stays vivid, and hypoallergenic for sensitive skin. Light on the wrist, it wipes clean in seconds and is built for daily wear, sport and travel. The adapter case is precision-machined for a secure, scratch-free hold.

Rubber, ceramic or steel

Pick the material above. All three are built around the same Royal Pop geometry, all three fit crown at 3 and crown at 12, and all three come off whenever you want the original lanyard back.

• Rubber — premium FKM rubber on the bioceramic adapter case: light, water- and sweat-resistant, hypoallergenic, and the widest colour range. The Link strap version keeps the same comfort in a moulded link pattern, closed by a concealed magnetic clasp that adjusts without a tool. See the rubber strap for the Royal Pop.
• Ceramic — polished ceramic links with a stainless-steel deployant clasp, sized link by link. Scratch-resistant, fade-proof and dressier than rubber. See the ceramic strap for the Royal Pop.
• Steel — an integrated stainless-steel bracelet and octagonal case machined in one piece, in gold or silver, with a concealed folding clasp released by two push-buttons. Real weight on the wrist, and the closest this gets to the watch it references. See the steel strap for the Royal Pop.

On the steel version, gold warms the darker dials and silver keeps the pastels crisp — the crown cut-out is machined per model either way, which is why you pick your Royal Pop above.

Wear the red loud — or mix it

This set is tuned to the Otto Rosso's red identity, but every WatchCollab Royal Pop strap and case is cross-compatible. Keep it tonal, or contrast it with another colour from the family. Fancy a cooler "eight"? See the Royal Pop Làn Ba strap & case and its deep blue.

How to fit your Royal Pop Otto Rosso strap and case

1. Remove the Otto Rosso from its lanyard.
2. Seat the watch head into the WatchCollab adapter case until it clicks securely into place.
3. Attach the rubber strap and adjust to your wrist.
4. Check the hold with a gentle pull — there should be no play. You're ready to wear.

Caring for your strap

Rinse the red strap with fresh water after heavy sweat or exposure, and clean it with mild soap and a soft cloth. Avoid harsh chemicals and prolonged direct sunlight in storage. With minimal care, the FKM rubber keeps its colour and suppleness for years.

FAQ

Which material should I choose?

"Otto Rosso" is Italian for "eight red" — a nod to the eight screws of the Royal Oak, rendered here in the collection's boldest red.
