Cyma 'Dirty Dozen' Watches at Auction 

During the Second World War the British Ministry of Defence (MoD) ordered timepieces from 12 watch companies for use by British troops on the front line. Cyma was one of the famed 'Dirty Dozen' watchmakers, producing 20,000 timepieces of the total 150,000 order. The Dirty Dozen wristwatches are incredibly sought-after by collectors keen to complete the set! Characterised by their 'W.W.W' inscription to case back, broad arrow to dial, black dial, arabic markers, luminous dots and hands within a stainless steel case, these watches are certainly worth selling at auction.  Dirty Dozen timepieces were produced by Buren, Cyma, Eterna, Grana, Jaeger-LeCoultre, Lemania, Longines, IWC, Omega, Record, Timor and Vertex - examples of each sell exceptionally well through our specialist sales. For a free and confidential valuation of your Dirty Dozen wristwatch, contact our specialist.
