I can see why the AF selected the Casio G-Shock to issue the SUPT students ... bulletproof, good and solid, large displays, and easy to use watch. I personally wear the new Citizen
Stealth (newest model of the Citizen
Blue Angel style line - looks just like it, but all black), but I have the Casio G-Shock to use for "huntin' wabbit".
I forget at the moment if the Casio is so equipped because I use it only for telling time, but if you're looking to save a little money on a "pilot's watch", IMHO it's only weakness is no ability to display dual time-zones, e.g., UTC. Otherwise, best $50 at Wal-Mart you can spend. When it comes down to it, all the fanciest IAP in the world needs as far as your wrist is concerned is START and STOP and RESET buttons, eh?
Now, if you want to go beyond simply functional, I highly recommend the Citizen chronos. I flew and flight instructed in them, and they have everything you need, and then some. Breitling is of course an excellent watch, but to me that's like putting a gold-plated saddle on a horse. I've met quite a few other pilots who "fly Citizens", and we luv 'em!
Oh, compare prices before you go buy a GOOD watch ... then go to eBay and get a deal! I carefully researched the seller of my
new (used --> you're on your own - not recommended) Citizen, and I saved a ton of money (and no tax - my
FAVORITE part!). My watch arrived in perfect condition, and I couldn't be happier.
