Manx

The Mercier Prototype Manx is notable as a Belgian-designed, veteran-owned microbrand automatic that avoids inflated or ambiguous specs, instead publishing straightforward, verifiable technical details. Its use of 316L steel with black PVD, a Japan-made Miyota 9122 automatic movement, 10 ATM water resistance, and a domed sapphire crystal positions it as a robust, honest daily watch with modern durability at an accessible level. The individually numbered pieces and transparent spec philosophy give it particular appeal for collectors who appreciate candor and tool-watch practicality in emerging microbrands.
