The Watch

.

At the start of the 1970's, the need for war died down and as military spending was reduced in Britain's Forces, the quality of watches produced consistently followed this as a consequence. The Ministry of Defence's DEF-STAN (Defence Standardization) was altered in order to produce more commercially viable pieces for the military.

.

The result of this was the creation of watches over a decade. Despite the change in specs, these watches followed the specifications of its predecessor, the Lemania Monopusher as it remained housed in a 39mm asymmetric stainless steel case and consisted of a black dial with luminous hands and markers. The change was that instead of one chronograph pusher, you now had two. As such, the movements that powered these pieces were the workhorse cam activated Valjoux 7733.

.

 The 4 companies chosen were: Hamilton, CWC, Precista and Newmark.

.

Today's example is in fantastic condition and was issued to the Royal Air Force in 1981. Precista only supplied these Watches for one year, meaning they are one of the rarer of the four to find.
