I'm sure that this gets brought up quite a bit, but are people happy with their G-Shocks? I generally beat the crap out of anything that I have, especially my watches, since they are with me all the time. Also, I thought that G-Shock came with an altimeter in them? I was reading through the product descriptions on their website and was a bit dissapointed in finding out that they don't. Or a thermometer. Anybody know of any worthwhile watches that have these things? Or should I go with a G-shock and enjoy it? Thanks for the help.
