Classic and functional
Color: Stainless Mesh/ Blue Dial
High quality and affordable watch. Love the mesh band. It’s a classic, functional everyday look. Easy to adjust, and never runs out of power. Perfect for men who have smaller wrists. Bought for my husbands birthday, and he loves it.

Everything as expected
Color: Stainless Mesh/ Blue Dial
It's a nice watch added to the collection, looks really good on hand, the metallic mesh band is very elegant and also customizable, so it will fit perfectly on your hand.
It seems that it had a bit of charge out of the box, but I'll leave it under a direct (under 20cm distance) LED desk lamp to recharge overnight, I'll also leave them under sunlight around the windows whenever possible (at least for the first week or so), it's stated in the online manual that it will need ~45 hours to fully charge on a cloudy day under the sunlight.
By the way, it would've been nice to have the manual in the box, but at least it's easy to find the (generic) manual in their website.
The fluorescence of the hands and hour dots are really bright and mine had nice bluish color.
Of the features, the chronograph works perfectly as expected, the manual also states to set the time 5 minutes ahead of the real time then slowly rewind back to the current time whenever setting the time, for the time keeping to be more accurate because of some gear movements inside.
To be honest, it would be great to see Citizen use scratch resistant sapphire instead of some mineral as the face protective layer, as they do for other high-end models, the technology is not new and I think it wouldn't make it that much more expensive, I hope this one will be resistant enough🤞🏻
Overall, this is the first day I received the watch, I'm quite happy with my purchase, it's nice knowing you won't need to replace the battery anytime soon 😛

Great watch for the money
Color: Stainless Mesh/ Blue Dial
Looks great. I swapped out the band for a leather strap. Nice watch, well designed. My other eco drive has been going strong for 15 years or so without a hitch. So I have high expectations for this one.
