Every model in the AP x Swatch Royal Pop collection spells the number eight — the eight screws of the Royal Oak — in a different language and colour. The Blaue Acht is the German one: "blue eight," a bright, precise blue that feels sharp and modern. Like every Royal Pop, though, it ships on a calfskin lanyard alone, so it stays a pocket watch. This Royal Pop strap & case set — part of WatchCollab's Audemars Piguet x Swatch straps — changes that: it turns your Blaue Acht into an everyday wristwatch in seconds, with no modification and no compromise on that vivid blue.
Built around the exact case geometry of the Royal Pop, the set pairs a colour-matched blue FKM band with a precision adapter case, so your Audemars Piguet x Swatch Royal Pop Blaue Acht finally moves from pocket to wrist — and back whenever you like.
The Royal Pop Blaue Acht: eight, in blue
The Blaue Acht keeps every Royal Oak cue — the octagonal bezel, the eight hexagonal screws, the Petite Tapisserie dial — in a bright, precise blue, powered by a hand-wound SISTEM51 movement with over 90 hours of reserve. Where the Làn Ba goes deep and understated, the Blaue Acht is the punchier, more vivid blue of the family — a colour that pops on the wrist and belongs there, not in a drawer. Our strap and case set is built to keep it on.
From pocket watch to everyday wristwatch
Out of the box the Blaue Acht 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 blue 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 blue 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 blue stays bright, 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.
Bright blue — or a warmer contrast
This set is tuned to the Blaue Acht's vivid blue identity, but every WatchCollab Royal Pop strap and case is cross-compatible. Keep it tonal, or warm it up with a brighter colour from the family. Fancy something bolder? See the Royal Pop Otg Roz strap & case in pink.
How to fit your Royal Pop Blaue Acht strap and case
- Remove the Blaue Acht 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 blue 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.
