Every model in the AP x Swatch Royal Pop collection says the same word — eight, for the eight screws of the Royal Oak — in a different language and colour. The Ocho Negro is the Spanish one: "eight in black," the stealthiest, most understated member of the family. Like every Royal Pop, though, it ships on a calfskin lanyard alone, so this all-black icon never makes it onto a wrist. This Royal Pop strap & case set — part of WatchCollab's Audemars Piguet x Swatch straps — changes that: it turns your Ocho Negro into an everyday wristwatch in seconds, with no modification and no shine added to that pure blackout look.
Built around the exact case geometry of the Royal Pop, the set pairs a colour-matched black FKM band with a precision adapter case, so your Audemars Piguet x Swatch Royal Pop Ocho Negro finally moves from pocket to wrist — and back whenever you like.
The Royal Pop Ocho Negro: eight, in black
The Ocho Negro keeps every Royal Oak cue — the octagonal bezel, the eight hexagonal screws, the Petite Tapisserie dial — in a deep, monochrome black, powered by a hand-wound SISTEM51 movement with over 90 hours of reserve. Stealth done properly: no colour to clash, nothing to date. It's the version that belongs on a wrist every day, not shut in a drawer, and our strap and case set is built to put it there.
From pocket watch to everyday wristwatch
Out of the box the Ocho Negro 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 black 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 black 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 black stays deep and matte, 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.
Total blackout — or a pop of colour
This set is tuned to the Ocho Negro's all-black identity, but every WatchCollab Royal Pop strap and case is cross-compatible. Keep the full stealth look, or break it up with a brighter band from the family. Want to add some heat? See the Royal Pop Orenji Hachi strap & case in orange.
How to fit your Royal Pop Ocho Negro strap and case
- Remove the Ocho Negro from its lanyard.
- Seat the watch head into the WatchCollab adapter case until it clicks securely into place.
- Attach the rubber strap and adjust to your wrist.
- Check the hold with a gentle pull — there should be no play. You're ready to wear.
Caring for your strap
Rinse the black 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.
