The Vertex MP45 is a watch we?ve covered here on Worn & Wound for a few years now. The brand is perhaps best known among modern enthusiasts collectors as a member of the so-called ?Dirty Dozen,? a maker of Ministry of Defense spec watches that were issued to military personnel in the World War II era. Those original Vertex W.W.W. (shorthand for ?wrist, watch, waterproof?) watches are highly collectible because compared to the other firms charged with producing these watches, IWC and Omega among them, Vertex was quite small. The brand eventually shuttered, and like so many heritage brands has resurfaced in the era of the vintage reissue, and the MP45 could be considered something of a flagship for the brand. It combines an old school military look with one of our favorite complications: the monopusher chronograph.
