Wear your AP × Swatch Royal Pop Green Eight on the wrist.
The Green Eight Royal Pop Monocoque is the first British-machined aluminium wrist case engineered for the Audemars Piguet × Swatch Royal Pop Green Eight. Milled from a single block of 7075 aerospace-grade aluminium at a precision engineering facility in Bicester, Oxfordshire. The same facility manufactures components for Formula 1, MotoGP, and aerospace clients.
The 7075 aluminium is supplied to AMS 4124 (Aerospace Material Specification) by a UK aerospace metals stockist whose approved supply chain includes Airbus, Bombardier, Leonardo, and Rolls Royce. Material certified to ISO 9001, AS/EN 9100, and EN 9120 - the aerospace industry's quality management standards. The same alloy is used for aircraft structural parts and motorsport gears and shafts.
Most aftermarket Royal Pop wrist solutions are cast ceramic, moulded FKM rubber, or injection-moulded plastic. The Monocoque is none of these. It is a structural aluminium case milled to motorsport tolerance, designed as a serious aftermarket accessory for the most-discussed watch launch of 2026.
For the AP × Swatch Royal Pop Green Eight variant. Lépine case, crown at 12. The Royal Pop watch is sold separately.
Choose your Monocoque case colour and FKM strap colour at the variant selector above. Five aerospace-grade aluminium case colours. Twelve FKM strap colours. Sixty possible combinations to make your Green Eight your own.
The Green Eight is the English-named Lépine in green. Light green Bioceramic bezel and crown, deeper green tapisserie dial, eight light green hex screws welded to the case. The cleanest tonal expression of the Royal Pop design language, with a single colour family running from bezel through dial to hex screws. The Silver Aluminium Monocoque case is the clean foundation that lets the green palette read as the visual focus. The Black Aluminium case provides the monochromatic contrast that makes the green dial and bezel pop. Both options complete the Green Eight's unified colour story without competing with it.
Specifications
Why British manufacturing
Most Royal Pop accessories are manufactured in China, with branding applied in Europe, the United States, or elsewhere. The Monocoque is different. Designed in Britain, engineered in Britain, and manufactured in Britain at a precision facility that supplies Formula 1 teams and aerospace clients. The aluminium is sourced through a UK aerospace supply chain. The intellectual property is registered to MGB Watches. UK shipping. Full UK Consumer Rights Act protection.
Material credentials
Each Monocoque is machined from AMS 4124 specification 7075 aluminium. The material is supplied by a UK aerospace metals stockist whose customers include Airbus, Bombardier, Leonardo, and Rolls Royce. Material certification is available on request with every order.
MGB Watches predicted the Audemars Piguet × Swatch collaboration in January 2024. Eighteen months before official confirmation. The Monocoque is the same diligence applied to engineering aftermarket product design.
