  • Remarkably easy to use for so many features
    Verified Purchase

    This is an almost perfect "wear everywhere" watch--has enough features to be considered a sports watch, but classy enough to be worn at the office. The atomic feature, as well as the other dials, are simple to use--much easier than you'd guess. With the perpetual calendar (including day of week), eco-drive, and radio controlled atomic time feature, this is a watch that you never need to fiddle with. No adjusting the date, no adjusting the time, etc. Throw in sapphire crystal and you've got an almost perfect watch for being attractive, useful, and low maintenance. Final note: for the atomic feature, I found that it works much better if you have it on its back near a window,, with the 6:00 end of the dial pointing towards Colorado (or wherever your radio transmitter is). The only thing I could do without is the tachymeter on the bezel (who uses those things?), but even that's done tastefully enough that it's not a problem.

  • Great looking watch

    I really like this watch, my reservation is that setting the time is complicated. And, when I first got it I had to wait until it had enough charge to be able to set it properly. Not that I am impatient.

  • Citizen watch - Not a new watch
    Verified Purchase

    This is not a review of the product but review of the condition of the product we received. Excellent watch but NEVER buy from Overstock. We got this today with multiple scratches on the strap (below the dial) and in a worn out & old box. There was dust on the inside of the box and even the watch was dusty. It was advertised as a new watch but it is definitely not a new one. Will have to re-consider buying anything from Overstock ever again unless the return is processes smoothly and I receive 100% refund!
