Crikey! That looks like it would survive a nuclear war!
Clever stuff though, with the radio updates. Although personally I prefer analogue and good old 'hands' to digitals. I find it easier to 'visualize' the time that way. Especially for last landings, FTLs and such.
Rugged though they undoubtedly are, I've never personally been a huge fan of 'Tupperware watches'. Well, with the exception of Swatch anyway. I've had a few of those in the past. I used to wear them when I was working on electrical systems for a living as they're non-conductive, so I wouldn't get a nasty surprise if I stuck my hand behind a panel somewhere and the watch shorted out anything live.
Wonder if Jock's new Vostok has turned up yet? I want to know what he thinks of it!
