CitizenMen's Eco-Drive Promaster Skyhawk A-T Watch, Brown Dial, Brown Leather Strap, Atomic Timekeeping (Model: JY8084-09H)

I'm a fan of Citizen watches, both for their look and their practicality. I have a Nighthawk that's over 15 years old and it still runs like a champ. The only thing it didn't have that I wanted was radio controlled timekeeping.Enter the Promaster Skyhwak A-T. It does it all and it's gorgeous.Just some of the features I use:1. UTC time (formerly Grenich Mean Time) I am an amatuer astronomer and I do a bunch of astrophotography. Times are almost always given in UTC, so having that on my watch is very handy, and allows me to set local time and the world time of my choice, for three separate clocks.2. Two time clocks for monitoring time in different regions. We travel a bunch and that means we're often in a different time zone. This watch lets me know what time it is back home, minimizing the 2am phone calls.3. Stop watch. Astrophotography is time depedant for long exposures, and knowing when your target is available and for how long is critical. The stop watch/timer lets me keep track of that so I never accidentally miss the shot.4. Alarms. I don't need to travel with an alarm clock. I have one on my wrist. It backs up my watch, which I've learned to snooze in my sleep. Can't do that with the watch!5. The slide rule bezel. Yes, I'm a nerd. I love slide rules, and the one on this watch is fully functional, including for conversion factor. Gallins to liters, miles to kilometers, and so on. As a Skyhawk, there are also plenty of flight calculations and conversion built into it.6. Atomic time keping. This watch synchronizes with the atomic clock each night, ensuring that you're watch is acorrect up to a fraction of a second. Now, this requires a bit of exlpanation.The time signal is sent out from a centralized location in America and Europe, China and Japan. A radio in the watch attempts to receive that signal three times a night. Two are hard coded in; one is adjustable. At these times, the watch "listens" for the time code. You can adjust it to pick up the correct signal for the area you are in. If it picks up the signal, then your watch will adjust itself to the correct time. If not, you can run the search manually, or just wait for tomorrow night. I live in the mountains of East Tennessee, pretty far away from the signal source. My watch updates about once or twice a month.I can increase that by wearing it to bed, since my body apparently acts like giant antenna.One thing I'd like to see added to the citizen is someway to determine the time and date of the last successful update. The only thing you can check is whether the last attempt wa successful or not.7. Eco drive. Light powers this watch, and if it lasts as long as my Nighthawk, I'll be supremely happy. No winding, no auto winding, no batteries and no dead atches. If there's medium bright light, it's charging. There's an indication of the charge on the dial, and the instructions say a full charge will last for weeks, if not months!Final note, it is a handsome watch. The brown leather strap sets off the gold bezel and silver body of the watch. The black dial and white markings create an easy to read watch face. And that remonds me of the final feature I use.8. The back light. The Nighthawk does not have a back light, and the glowing hands never really worked well for me. The Skyhawk, on the other hand, is very easy to read at night.All in all, I'm very happy with this watch, and will purchase another Citizen down the road. There's a Calandrier I have me eye on...

Todo llego a tiempo y en perfecto estado

Great sports watch for all around activities. Great for Dress up too.
