Vertex Watches, located at 15 Shepherd Market in Mayfair, London, is a historic British watchmaker founded in 1912 by Claude Lyons. Renowned for its military heritage, Vertex was the only British brand among the "Dirty Dozen" watchmakers commissioned by the Ministry of Defence during WWII to produce robust, legible timepieces for soldiers. Revived in 2016 by Lyons’ great-grandson, Don Cochrane, the company operates from a charming Georgian townhouse, featuring a compact showroom with mid-century memorabilia and a WWII-era BSA M20 motorbike. Vertex crafts modern tool watches, blending Swiss engineering with British design, including the M100 series and M60 AquaLion, celebrated for their durability, luminous dials, and nod to military history
