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 strap & case set for Royal Pop — part of WatchCollab's straps for Royal Pop range — 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.
This model page brings together rubber, ceramic and steel options. Choose the material before comparing the available colours: the finish, fastening and adjustment depend on the version selected.
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
The set is designed to let you wear the Royal Pop on your wrist using a strap and an adapter case. Compare the photographs of your selected version to see how the case, strap and fastening fit together. The watch is sold separately.
Built for the Royal Pop's exact geometry
Select your Royal Pop model and check the position of its crown against the adapter shown for your selection. The fitting and fastening can differ between rubber, ceramic and steel versions; follow the instructions for the set you receive.
Premium materials, all-day comfort
Rubber gives a flexible strap; ceramic offers a polished link finish; steel provides a metal bracelet. Compare the appearance and adjustment of each version in the product options. Colour availability varies by material.
Rubber, ceramic or steel
Select a material and colour above to view the corresponding version.
- Rubber — a flexible strap option. Check the selected design for its fastening, colour and adapter. See also: rubber strap for the Royal Pop
- Ceramic — polished links with a stainless-steel clasp. Adjust the bracelet by sizing its links and avoid hard impacts. See also: ceramic strap for the Royal Pop
- Steel — a metal bracelet and adapter with a matching finish. Compare the gold-tone and silver-tone options available for your model. See also: 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 strap and case for Royal Pop is cross-compatible. Keep it tonal, or contrast it with another colour from the family. Fancy a cooler "eight"? See the strap & case for Royal Pop Làn Ba and its deep blue.
How to fit your strap and case for Royal Pop Otto Rosso
Place the watch on a clean, soft surface. Identify the adapter, fastening and adjustment instructions for the selected set before assembly. Fit the parts without forcing them, adjust the strap to your wrist, then check that every fastening is secure before wearing it.
Caring for your strap
Wipe the strap and adapter with a soft cloth and dry them before storage. Follow the care instructions for the chosen material, and avoid abrasive products and hard impacts. A strap or adapter does not change the watch’s water-resistance rating.
Why WatchCollab
WatchCollab designs independent accessories built to the exact specs of collaboration watches like the Royal Pop Otto Rosso — a purpose-made fit, not a generic band, plus a wide, cross-compatible colour range. WatchCollab is not affiliated with Audemars Piguet or Swatch, and the watch is not included.
FAQ
Which material should I choose?
Choose rubber for flexibility, ceramic for a polished link finish, or steel for a metal bracelet.
Why is it called "Otto Rosso"?
"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.
Can I wear the Otto Rosso as a wristwatch with this set?
Yes. The set converts the pocket watch into an everyday wristwatch and removes cleanly whenever you want the original lanyard back.
Will it damage or alter my watch?
The set is removable. Follow the fitting guide and check the watch and adapter are correctly aligned before fastening; avoid forcing the case into place.
Is this an official Audemars Piguet or Swatch product?
No. It's an independent WatchCollab accessory, compatible with the Royal Pop. The watch itself is not included.
