Don't Waste Your Money
Color: Retro Brown band & Gold bezel & White dial
This watch is a complete disappointment. Right out from the box, I adjusted the time per the instruction manual. After finshing adjusting the watch, I pushed the crown in (two clicks). The second hand started movement after almost 10 seconds. From then on, the second hand was stopping and going by itself. Within less than anhour, the watch was behind almost 25 seconds. It is a piece of junk. I would not advise anyone to buy this watch.

Rough dial, pretty watch
Color: Mesh Strap watch balck
Great looking watch, the dial is rough on the skin, it should be refined some to not have sharp edges.

Great Watch for a Great Price
Color: Dark Brown band & Rose Gold bezel & Navy Blue dial
⌚ “Simple, clean, and gets compliments every time.” ⌚
This Watch has easily become my go-to watch.
What I like most is how clean the design is. It’s not flashy, but it stands out in a classy way. I usually pair it with brown shoes and a belt, and it pulls the whole look together perfectly.
Another big plus—it doesn’t feel heavy on the wrist. You can wear it all day and forget it’s even there, which is exactly what you want in a daily watch.
And the compliments? They come consistently. It’s one of those pieces people notice without you trying too hard.
✔️ Clean, stylish design
✔️ Lightweight and comfortable
✔️ Pairs perfectly with dress or casual outfits
✔️ Gets a lot of compliments
If you’re looking for an affordable watch that looks sharp and feels great, this is a solid choice.

Unusable Adjustment Diagram – Completely Black
Color: Mesh Strap watch silver balck
The watch itself looks nice, but there is an issue with the instructions for adjusting the band. The included diagram is completely black and does not show how to make the adjustment.
I was only able to adjust the band because I had a diagram from a previous watch. Without that, it would have been very difficult.
The manufacturer should provide clear and readable instructions.

You won’t be disappointed with this one
Color: All Golden face Big Dial
Looks great fits great I was skeptical about getting it because I purchased another variation and was not happy at all but I like the way that this one looks so I said I’d give it another shot. I’m glad I did. I’m very impressed with it.
