Ok, so they are RAF watches, that helps. The 2384 and 2179 are Omega watches, but for the US army so it won't be one of those.
No 2 could easily be a Dennison 12322 case that was used to house what are called 'economy 6B' watches, several manufacturers Waltham, Ebel etc. Either 6B/159 or 6B/234. It looks like the dial on no 2 had lumed numerals though.
If RAF the pocket watch won't be a GSTP but a 6E/50 or similar.
Regarding the tank watch I don't know of an issued tank style watch, others will know more, so it was probably a privately purchased watch.
