There are some belters there, the Lemania (£2-3000?) and Newmark (£1750-2500?) chronographs, the Smiths (£4-5000?) immediately caught my eye.
CYMA and Lemania WWWs (£1000 - £1500) each? RAF Omega £1500-2000?
For the military watches, MWR is a way to find values and sell individual watches.
For ease, then I guess go to an auction, WoK or something like that?
Ps. These valuations were fairly cursory from my memory of what might be initially asked by someone selling on MWR. As someone has pointed out below, optimistic in that a dealer would offer less and less achievable at auction.
