Notes: In the second half of the 40s, the British Ministry of Defense commissioned military wristwatches for soldiers;  twelve were the manufacturers that responded to the requirements of the Ministry: Buren, Cyma, Eterna, Grana, Jaeger-LeCoultre, Lemania, Longines, IWC, Omega, Record, Timor and Vertex. These twelve watches are known among collectors as the "Dirty Dozen".
