An accessible-luxury automatic watch — Belgian-designed, individually numbered, and built to be worn, not feared.
Designed as an everyday luxury watch, the Manx balances elegance with resilience — a true retro-racing automatic watch with a tachymetre bezel, day & month complications, and a flash of racing red. A Japan-made automatic movement, a domed sapphire crystal, and a 316L steel case finished in black PVD. Individually numbered. Made to keep time through a life actually lived.
The blacked-out Noir or the crisp white Blanc — the same automatic heart, two ways to wear it. See the full collection and reserve your individually numbered piece.
No heritage premium. No boutique markup. Just the watch, the math behind it, and the maker who stands behind every numbered piece.
316L stainless in black PVD, 42mm. The caseband itself is engraved — Protoforce · Sapphire Crystal · Stainless Steel · 10 ATM.
An exhibition caseback frames a self-winding Miyota automatic — visible, honest, and serviceable by any watchmaker.
Sized and built to disappear into a real day — the watch you actually wear, not the one you're afraid to.
Mercier Prototype was built by one person who could never find the watch he actually wanted — so he made it. Every Mercier is designed by him. Each case is serial-numbered. Each component is chosen to do its job, and then a little more. There is no heritage premium. There is the watch, the math behind it, and the person who made it.
Independent press and an industry award — before the first run has even shipped.
