Total piece of Junk
Color: Gold
Great looking watch, but unfortunately it is a total piece of junk. Almost impossible to set, changes time while sitting and battery dies within a week. Don’t waste your money.

Cannot adjust watch band
Color: Black
There is no way to shorten the band despite the crap tool and instructions. Sad because it is a nice watch

Do Not Purchase- junk
Color: Gold
Do not buy. Cheap, cheap, cheap! Directions on how to fix the plastic band are for a different watch. I cannot remove links and it is too big! Do not purchase! Only gave it one star because I had to. Would give no stars, but it wouldn’t let me publish.

Great value for vintage inspired wristwatch
Color: Brown White
I was struggling to find a brown silver leather wristwatch that was under $50, but this watch meets all my needs and looks timeless. I like the leather strap a lot because it is thin and looks polished. The leather is a really rich brown color that looks very elegant. The strap is also comfortable for my everyday wear and is not prone to scratches. The face is also the perfect size for my wrist and gives the vintage feel that I was looking for. Overall, the quality is great for the price point and I really like this watch!
