CitizenMen's Promaster Air Skyhawk Eco-Drive Super Titanium™ Watch, Atomic Timkeeping Technology, Power Reserve Indicator, Luminous, Anti-Reflective Crystal, 45mm (Model: JY8108-53E)

Full disclosure: I wound up returning this watch.I am a military pilot so an accurate watch with Zulu (UTC) time is very appealing. I found the setup to be pretty simple by following the instructions. Most features on this watch are used by simply turning the crown to the desired setting and cycling through the lower button - the upper button doesn't seem to be used for much other than the backlight.The build quality is fantastic. With the bracelet, it's lighter than my (smaller) glycine combat sub on a NATO. It feels rugged, sturdy, but still retains fine details and precise clicks. The main hands are clear and visible with good contrast despite the busy face, which was a pleasant surprise when I saw the watch in person for the first time. The watch itself just looks awesome and was complimented the first time I wore it.what I didn't like:There is a small dedicated 24hr UTC dial at the top of the face. Due to its small size, it is obscured by the main watch hands for like 20 minutes every hour (between :50 and :10 on the minutes) and between the hours of 11 and 1 o clock. Effectively a useless dial to me. You can put UTC time on the small digital display which is nice, however you now lose out on having a day/date display (which I love having because I am dumb and forget what day it is constantly).The E-6b bezel is cool, and despite its small size, the numbers are crisp and legible. I used it for a fuel check a few times for laughs while flying. Obviously unless you take it off, you're going to be reading numbers upside down. One thing I didn't care for is that the inner ring of the computer is under the crystal, which makes an odd contrast. Older versions of the watch had the entire E-6b outside the bezel.Finally, the thing I disliked most and the reason I ultimately returned it: the size. It's massive. I wanted a rugged, accurate watch I could wear 24/7; deploy with, something to become a part of me. I felt like a clown wearing this watch, like a child who snuck into his dad's room to wear his clothes. It was so big I felt like someone strapped a hockey puck to my wrist. If you're a gorilla man, it'll probably work for you. I was blessed with 6 1/2" wrists and it absolutely did not work for me. As much as I liked the features of the watch, I felt so ridiculous wearing it that I rarely did and ultimately sent it back.If you like big watches, or you're a big dude, it's great. I looked at thousands of watches looking for something with this many features and there is nothing else that comes close, even among $5000+ watches. If you've got smaller wrists, I'd pass.

This watch is awesome. I even like the orange highlights on the bezel. I use the multi-time zone feature, and the circular slide rule for doing flight computations is super geek. I learned how to use one of these when I was a kid getting my pilot's license. The watch control interface can be a bit challenging at times, but as this is my third Citizen watch, it is very similar and consistent with the previous watches. Note that the battery in these solar watches will die after 10+ years (like an EV) and can be replaced, but by then you may as well get a new watch anyway as there will be some amount of wear in that time. I get a smile on my face every time I look at this watch!

My third eco-watch. All have been great. This one is beautiful and functional. Love the titanium finish and lighter weight.

Great looking watch for guys who like aviation watches, or just watches in general. I have XL sized hands and it fits nicely.

The media could not be loaded. I am very happy with this purchase!Great quality and fast shipping!

I really liked the watch until 10 months in, with the exception being the annoyance of having to switch between calendar mode and dual time mode; you can't display both simultaneously . After 10 month the crown and stem completely disengaged from the watch when I pulled the crown as usual to adjust the mode. You would think this is covered by warranty. Not so. Citizen apparently exclude the crown from warranty (Seiko, their main competitor, does not), and therefore I was initially quoted over $350 to repair it. To me that is inexcusable, especially when a brief Google search shows others have had the same issue. My guess is that whatever internal part keeps the stem in place is of poor quality, and/or the need to frequently switch between calendar and world time modes inevitably wears out the part that holds the stem in place (in which case it is a design flaw).

Got this for my sons graduation. I own 10 eco drives and this one stands out. Very large face and a nice contrast between the bracelet and the watch. He likes it and I have to remind him to save it for special occasions.

Perfect watch, enjoying its simplicity and luxury look!
