 The M100’s dial echos the original Vertex WWW model, from the font, to the minute track and the hour markers. However, the modern design boasts the very best X1 grade Super-LumiNova. The spectacular lume has been cast into solid blocks, ensuring unparalleled clarity and an enduring, signature Vertex glow.

A British Classic Reinvented

100 years since Claude Lyons started the company, Vertex is re-incorporated by his Great Grandson, Don Cochrane.

The M100

The M100 is the ultimate homage to the legendary Vertex WWW Cal 59 - worn by
the soldiers, sailors and airmen during WW2  

With meticulous care to maintain the essence of the original specification, the 21st century version is modernised to embrace the very best of today’s watchmaking technology. 

Its top specification Sellita SW260-1 movement is attached to ‘syringe hands’ and a sub second counter, which match the original perfectly. This is housed in the M100’s brushed steel 40mm case and locking crown, ensuring water resistance down to 100 meters.

As a reminder of the Vertex military heritage, each watch features a ‘broad arrow ’marking on the dial. - The British MOD has given Vertex specific permission to use this as a mark of historical relevance. 

The moulded SuperLuminova dial emits the signature and imitable Vertex glow, allowing perfect legibility in any conditions, no matter your current mission.
