The stitching is holding up well so far. Time will tell, but a great start.

The Royal Pop Ocho Negro strap converts your AP x Swatch Royal Pop pocket watch with a crown at 12 o'clock into a fully wearable wristwatch - no tools, no modifications required. Crafted from black FKM rubber with an integrated case, it fits all 6 Lepine models.
Unlike the Savonnette editions (crown at 3 o'clock, small seconds at 6 o'clock), the Lepine features a crown at 12 o'clock with no small-seconds subdial. The Maison Brassel integrated case is purpose-built for this configuration, keeping the crown accessible and the dial perfectly legible on the wrist.
Maison Brassel is not affiliated with Audemars Piguet or Swatch. All brand names are used solely to indicate compatibility.
The strap is not an accessory to the watch. It is its silent soul.
Maison Brassel was born from a simple conviction: most great watches deserve a strap that lives up to them. Too often, the original strap is nothing more than a default option. We offer another path, one where the strap is thoughtfully designed, drawn, and crafted as a true extension of the timepiece.
Our vision can be summed up in a few words: the right proportions, the right material, the right finish. No ornament. No noise. Respect for the caliber you wear.
Our products are covered by a 24-month warranty from the date of shipment. It does not cover any damage to any part of the product resulting from abnormal use, lack of care, negligence, accidents, incorrect use, or failure to follow the instructions provided by Maison Brassel.
All displayed prices include VAT. For orders shipped outside the European Union, taxes and any customs duties are also included, including for the United States, Canada, and other destinations.
Installation tutorials, close-up material shots, watches on the wrist: see the Royal POP Maison Brassel strap in video.

If your Royal Pop has the crown at 12 o'clock, meaning one of the 6 Lepine references (Huit Blanc SSX03W100N, Green Eight SSX03G100N, Ocho Negro SSX03W101N, Blaue Acht SSX03L101N, Orenji Hachi SSX03L103N, Otto Rosso SSX03R100N), pick a strap from the Lepine collection: its integrated case is fitted for the 12 o'clock crown, without a small seconds subdial. Then choose your FKM color from the 8 available shades. For a 3 o'clock crown (Làn Bā, Otg Roz), see the Savonnette collection.
Yes. Every Maison Brassel integrated case is engineered to the exact dimensions of the Royal Pop AP x Swatch module (40 mm), available in both crown positions (12 o'clock Lepine or 3 o'clock Savonnette) for a precise, play-free fit. And if the fit doesn't satisfy you, exchanges or refunds are free within 30 days, at no risk.
The only difference is the crown. The Lepine models have the crown at 12 o'clock with no small seconds subdial (6 models). The Savonnette models have the crown at 3 o'clock with a small seconds at 6 o'clock (2 models: Làn Bā SSX03L100N and Otg Roz SSX03J100N). The strap's integrated case is oriented according to the crown position, which is why there are two distinct collections: check your watch's crown before choosing.
Remove your Royal Pop from its original lanyard and clip it into the Maison Brassel integrated case: the FKM strap is already attached. The process is done by hand, with no tools or modifications, in under a minute, and is fully reversible.
Without the case, the Royal Pop module measures 40 mm. Once clipped into the Maison Brassel integrated case, the full assembly measures 42 mm, a common sports watch size and more wearable than the 44 mm often cited for this type of setup. If you have a very slim wrist, keep this presence in mind.
No. The watch clips into the integrated case without glue, screws, or cutting: you insert and remove it by hand. It is 100% reversible, and you get your original Royal Pop back in seconds.
Premium FKM rubber (fluoroelastomer), a high-performance rubber comparable to Rolex's Oysterflex: hypoallergenic, resistant to water, sweat, UV rays, and chlorine, and odorless. Care: rinse with warm soapy water and dry with a soft cloth. Avoid solvents.
No. Maison Brassel is an independent brand with no connection, partnership, or affiliation with Audemars Piguet or Swatch. We design straps and cases compatible with the AP x Swatch Royal Pop watch; the brands and references mentioned belong to their respective owners and are used solely to indicate compatibility.
