Watch Strap for Swatch x AP Royal Pop Làn Ba - Wear It on Your Wrist

The Swatch x Audemars Piguet Royal Pop Làn Ba (Ref. SSX03L100N) is the most universally wearable colorway in the collection. Deep blue case, sky blue dial — a double blue combination that works with everything. As one of the two Savonnette references, it features the crown at 3 o'clock and a small seconds subdial at 6, giving it the most wristwatch-ready layout of any Royal Pop. Our precision-fit strap puts it exactly where it belongs — on your wrist.

Why the Làn Ba Deserves Your Wrist

Làn Ba is Mandarin Chinese for eight blue. The deep blue and sky blue combination is the most versatile in the Royal Pop lineup. It pairs with formal wear, streetwear, and everything in between. As a Savonnette with the crown at 3 and small seconds at 6, the Làn Ba has the most natural wristwatch configuration of all eight Royal Pop references. The crown at 3 o'clock is where it belongs on a wristwatch — and the Làn Ba delivers exactly that the moment you put our strap on. The blue bioceramic case reads as both casual and refined — a rare quality in any watch at any price point. It is the Royal Pop for people who want to wear their watch every single day without compromise.

What Makes Our Làn Ba Strap Different

Our strap is built exclusively for the Royal Pop 40mm octagonal bioceramic case. A precision-fit system that clicks directly into the existing pop mechanism — the same coupler Swatch designed into the case from day one. No generic pocket watch adapter. No clamp. The Làn Ba clicks in and sits on your wrist with the crown perfectly positioned at 3 o'clock and the small seconds at 6 — exactly where a proper Swiss wristwatch should be. Precision-fit for the Royal Pop 40mm octagonal case, compatible with Làn Ba Ref. SSX03L100N, snaps on in seconds with no tools required, fully non-destructive and preserves the pop mechanism.

How to Wear Your Royal Pop Làn Ba on Your Wrist

Remove the Làn Ba case head from its lanyard clip by pressing the pop mechanism. Align the adapter with the octagonal case — the fit is exact, no force needed. Click it in. The mechanism locks with an audible click. Buckle the strap on your wrist. Total time: under 30 seconds.

The Làn Ba on Your Wrist — What to Expect

The Royal Pop Làn Ba sits at 40mm on the wrist — identical footprint to an Audemars Piguet Royal Oak 39mm Jumbo. The Savonnette layout — crown at 3, small seconds at 6 — is the most natural wristwatch configuration in the Royal Pop collection. The deep blue bioceramic is scratch-resistant and colour-stable. The pigment is compounded into the resin — it will not chip, fade or scratch through daily wear. The sky blue tapisserie dial catches the light beautifully at every angle. The Làn Ba is the Royal Pop that looks as good in a boardroom as it does on a weekend.
