The Audemars Piguet × Swatch Royal POP arrived as eight pocket watches with nowhere to land on the wrist. Lambertus picked up that gap on day one of the drop and called the answer Chapter I.
Chapter I is a tailored strap with a machined octagonal clip holder that snaps the Royal POP head in and out with no tools and no modification to the watch. Lambertus splits the lineup the same way Swatch and AP did, with Strap I for the six Lépine watches that wear the crown at 12 and Strap II for the two Savonnette watches that wear it at 3, and the brand pairs each strap with its own colourway across an eight-piece run. Pre-orders are open at $95 with free worldwide shipping through royalpopwristbands.com, paid in full to lock a place in the queue, and the storefront flags the program as Chapter I, an R&D phase with Prototyping, Final Design Sign-Off, Manufacturing, and Shipping still ahead on the public roadmap.

Why a strap brand jumped first
The Royal POP collab landed as a cult object the moment it dropped, with eight references and a global appetite that immediately outpaced the only form factor AP and Swatch put on offer. Lambertus’s pitch is blunt: the watch is “impossible on the wrist,” and Chapter I is “the only thing it was missing.” That positioning matters because it tells you Lambertus isn’t iterating on an existing strap line, it’s filling a category that didn’t exist forty-eight hours ago.
What’s actually in the box
The public spec sheet is short, but it’s all there. Strap I covers the six Lépine watches that wear the crown at 12, in Vantablack Velvet, Midnight Sapphire, Pistachio Soufflé, Verdant Reverie, Alabaster Hush, and Blush Atelier. Strap II covers the two Savonnette watches that wear the crown at 3, in Cobalt Mirage and Coral Confit. Every strap is $95 with free worldwide shipping, secure checkout runs through Shopify, and the mechanism is described on the brand site as a machined octagonal holder that snaps the watch in and out with no tools and no modification.
The Royal POP strap rush, in context
Lambertus isn’t alone in this race: Delugs has opened a public waitlist for Project WristPop, an open R&D case-strap effort with pricing still listed as “to be announced,” and product pages live for all eight Royal POP colourways. Grandeur USA’s Pop Case sits at the top of the price spectrum, an in-stock $450 wrist adapter built around an FKM rubber receiver and a color-matched cast-ceramic bracelet, limited to 100 numbered pieces per colorway, while Golden Concept has listed its own Pop Case at $449 with MotionBand, FlexLink, and alligator leather strap options, currently out of stock, and SANDS UAE is taking 2-to-3-week pre-orders for its Royal Pop Bracelet at roughly $163 through its Dubai storefront.
Wristbuddys has its Royal POP Straps collection page live with notify-me signups and pricing still to be confirmed, Helvetus has its full eight-reference Royal Pop Wrist Strap & Case collection live but every variant is sold out at a $0.00 placeholder with no public launch price, and a long tail of smaller makers is queued for the same window. That puts Chapter I into a crowded sprint rather than an open field, and at $95 it comes in as the lowest-priced option of the rush, undercutting Grandeur USA’s $450 and Golden Concept’s $449 by roughly 79 percent and SANDS UAE’s $163 by roughly 42 percent.
The angle for buyers
If you already paid $400 to $420 for a Royal POP and you’re happy wearing it the way AP and Swatch designed it (on one of three lanyard lengths, kept in a pocket, or parked on a desk stand), you don’t need Chapter I. If you bought the watch because the silhouette is half the joke and you want it on your wrist instead, Lambertus is the cheapest pre-orderable option at $95, while the other publicly priced options (Grandeur USA’s $450 Pop Case, Golden Concept’s $449 Pop Case, and SANDS UAE’s roughly $163 Royal Pop Bracelet) all run higher, and Delugs, Wristbuddys, and Helvetus are still on waitlists with no price published.
The catch is that the order is paid in full at the R&D Phase step of a six-step roadmap, with Prototyping, Final Design Sign-Off, Manufacturing, and Shipping all still ahead, so the brand is selling the queue, not a finished product.
