Cards don’t fit tight
Color: Black Embossed
My credit cards fall out. Needed a more secure alternative— still stayed with Tumi though.

Wonderfully made, but not well sized for US currency
This is a very nice slim billfold, but unfortunately, it's not well sized for US currency. Probably for Euros. US Dollars fit, but it's a touch too narrow across to easily insert a bill. So you'll have to very diligently straighten and align a greenback to make it fit.

Class and elegance
Color: Gold
I absolutely love this watch! My grandson also loved mine so I bought him one for Christmas. This is the 4th Citizen watch I have purchased. 2 are ecodrive and 2 are battery powered. I have to say I do like the battery powered watches better for their weight, lots lighter on your wrist than the ecodrive I regularly used to wear. This watch has taken a beating, as it seems like I'm always hitting the face on something, and has performed beautifully. I figured that I would've replaced the crystal by now but I haven't had to. My grandson admired and wanted mine, (I can't part with it because it has special meaning) so I bought him the identical model. I have worn mine in water, extreme cold, and out to dinner. It looks and performs beautifully. This watch is classy, elegant and beautiful and it's not a giant timepiece although you may have to take it to your local jeweler for band sizing. There's videos on u tube but I don't recommend trying that for taking links out. I say beautiful because as a woman wearing this watch it's not overwhelming and screaming look at me I'm wearing a man's watch. However this watch is handsome looking on men, my husband and grandson lol. The band is smooth, doesn't kink or pinch my wrist and when fitted properly it doesn't end up face down or sliding over and staying over on the outside of my wrist. Only drawback for me is I'm not used to the day dial and sometimes when setting the time bc some months are shorter I tend to be a day ahead, easy fix. I've gotten lots of compliments on this watch and would definitely buy it again

5-Star Review: Sleek, Reliable, and Worth Every Penny!
Color: Gold, Color: Gold
I recently purchased this Citizen watch, and I'm thoroughly impressed! The design is sleek and modern, perfect for both casual and formal occasions. The Eco-Drive technology is a game-changer-no battery changes needed, just sunlight or indoor light to keep it running. The build quality feels premium, and the stainless steel band is comfortable yet durable. It keeps time accurately, and the dial is easy to read. For the price, this watch offers exceptional value and style. Highly recommend it to anyone looking for a reliable, eco-friendly timepiece!
