Citizen JY0010-50E Review: Citizen Eco-Drive Skyhawk A-T Titanium Watch

June 5, 2010                                               Posted by:


The Citizen Eco-Drive JY0010-50E is dripping with cool features. This watch is the new, fully loaded 3rd generation Skyhawk. It sends and receives radio signals for time keeping via the Skyhawk A-T. Just looking at the screen of the watch you can tell there’s alot going on there.
To me it looks like the cockpit of a plane! And for some of you that’s exactly where you’re going to use it. But what are the actual features of this watch?

Citizen JY0010-50E Features:

  1. Atomic timekeeping with radio-controlled accuracy

  2. World time in 43 cities

  3. 2 alarms

  4. 1/100 second chronograph that measures up to 24 hours  

  5. 99 minute countdown timer

  6. Perpetual calendar

  7. Digital display light

  8. Greenwich Mean Time display

  9. Rotating slide-rule bezel

  10. Non-reflective mineral crystal

  11. Power-reserve indicator

Citizen JY10


The watch has 2 alarms, world time zones (43 cities), solar power, atomic time, a countdown timer, a chronograph, a slide rule, UTC time, a 24 hour clock, ultra-light and nearly indestructable titanium construction, 200 meter waterproof, mineral glass, and it looks outstanding. What more could you want? I think it even does the dishes, bathrooms, and windows. But I haven’t looked up those features yet in the 115 page manual (English portion).

One thing that’s missing is a one-touch feature to bring all hands to the 12 o’clock position to clear the LCD displays during certain times of day. The hands occasionally obscure your attempts to read the LCD’s. Another little gripe is you have to pull out and turn the crown to check the date. And it’ll show you the date of your second time zone only. You have to do a couple more steps to get your home zone date if your second time zone is across the dateline from you. I think there’s a way to set the LCD 2 to show the date all the time, but I haven’t figured out how to do that yet. (Correction 4/1/08: I don’t think there is any way you can get LCD 2 to show the date.)

Forget Rolex, Breitling, and Omega. They might look cool and have their high-falutin image, but they have nowhere near the functionality and practicality of this new Citizen. And they all cost about 10 times more. They are also much heavier.

Bottom line: It’s virtually indestructable, ultralight, maintenance and adjustment free. I never have to set the time again nor will I ever have to change a battery or put it in a watch-winder (for automatics). I’m a big fan and proud owner of one of the coolest watches on the planet.


  • Looks great
  • It is very-very well made.
  • It synchronizes perfectly both in the U.S. and in Europe (great for family members overseas)
  • Very light-weight
  • Two alarms so keep one on the local and the second on the world time if you wish
  • Solar powered (no charging ever!)


  • The back light though present is not the best
  • The hands cover the digital display a few times a day you can tilt and read under the hands but forget trying to set any function at 20 past the hour
  • If you are going to use the second display for a world time zone there is no way to see the local calendar. Just to see the calendar you have to pull the crown 1 stop twist to change the mode and that will give you the calendar of the world zone So to have calendar functionality for local zone you have to set the world zone as your local zone (you lose an easy way to see the world zone). Simply put this watch can work as a dual zone watch or as a calendar watch not as both.

Citizen JY0010-50E Summary:

So all in all this is a pretty groovy watch. It’s packed full of fantastic features and most people are very happy with their Citizen JY0010-50E.  It’s virtually indestructable, ultralight, maintenance and adjustment free. You’ll never have to set the time again nor will you ever have to change a battery or put it in a watch-winder.

It is rugged but elegant. The titanium looks good but also makes the watch light enough for wearing all the time without having to think about it. Some people complain the backlight isn’t bright enough, while others are adamant that it’s great. Close to a perfect watch, but it does have a few flaws.
