I got mine in Argos for about £20.
It's a Lorus, has a luminous green face which glows very well in the dark, all the numbers are very clear, as are the minute indentations for accurate time telling. I've met at least 10 other pilots who also wear this watch, as it is so clear and simple. It also gives day and date. I reset it about once a month, and it only drifts seconds from the GPS time in my aircraft.
The watch with the flight computer round the edge may make you feel more like a pilot, and show off to your mates, but in the cockpit keep it simple stupid!
