It’s alright
Color: Black Band and Black Face, Color: Black Band and Black Face
it’s a bigger watch definitely need to take some links out and the adjustment tools are not the best at all they break very easily. but other than that the watch is very pretty. it does have some weight to it but not completely heavy

Perfect everyday Watch
Color: Grey, Color: Grey
Super happy with this watch. It looks really clean and goes with pretty much anything dress it up or wear it casual. The blue face is fire in person and catches the light really nicely.
Feels solid on the wrist, not too heavy, and the quality is definitely there. I’ve been wearing it almost every day and it still looks brand new.
For the price, you really can’t beat it. Great everyday watch that looks way more expensive than it is. Would 100% buy again

Stylish and inexpensive
Color: Grey
Great watch. Came in quickly from seller. Got it sized at a local shop. It’s a pretty stylish watch for the price point. I don’t have big wrists but I still think the face could be a little bigger. But it’s pretty sleek and I’m happy
