I have a £40 Pulsar RAF issue one (same watch as £230 Seiko) which has the same look 'n' feel as the cockpit instruments so your brain picks out the info easily. I used to have an IWC when I was in the RAF, that 'shouted' the time at you!
I also have a Vostock Amphibian.
Look on eBay, there are a whole range of MWC, IWC, Seiko, Poljot and US ones, I might get one of the German Air Force issue ones next, they are reasonably simple in design, but look well-engineered
