If you want to tell the time any cheap digital does a splendid job.
If you want to look cool get a complicated analogue with a spinny dial, top drawer goes to the ones with no numbers on - guarantees you cant read the time. Although they do serve a purpose in the pub and mark you out from the crowd as a dashing aviator.
So the answer is Breitling for the pub, Casio for the air. If you wear both you have a standby for when the battery goes flat on the readable one.
BTW all you smuggies with the light powered citizens, mine stopped working after three years, just stopped, no reason, no amount of warming it under million candella lamps has persuaded it to work again. :-(
