Three decades ago, probably when they were decommissioned, the London watches markets had piles of MOD watches models, IWC, JLC, Precista, CWC, Newmark, Hamilton. At that time they were going for a max. of 100 British pounds ;-) (I know you wish you had been there LOL).
Anyway I find it good to see them re-surfacing, these watches have true histories and military specs
Here is a picture from the Watchlords showing the other brands of the same model, I believe all housing a Valjoux 7733
