I have a citizen skyhawk titanium eco drive. It's light as hell, a few coworkers think it's painted plastic. The eco-drive movement's pretty nice. Consider that 90% of the time if you have a button down desk job, your watch is in your sleeve and for a good 7-8 hrs a day it's in the dark while you're sleeping, the watch is smart enough to shut off the mechanicals if it senses no light for about 2 minutes. Once you lift your sleeve or expose it to light, it's quite a show to watch all the hands whizzing into their respective positions within about a second.
I've put it through about 3 years of heavy nonstop use, there are a few scratches on the sapphire and a whole lot of them on the band and casing, since I work with concrete sometimes and the chunks of quartz and whatnot in there really take a toll on the watch.
It's accurate enough that it loses or gains about a second every 3-4 months (yes mine's that accurate). Maybe I got lucky on the movement lottery or something. But it's very satisfying whenever I pull back my sleeve to check the time, have all the hands whiz back into their positions, and when the guy on the radio says "it is now 9pm, *beep*", my watch almost always lands right smack on 0 seconds when I hear the beep.
