Very stylish but not the best quality
Color: Silvery Gold green dial, Color: Silvery Gold green dial
You are getting what you pay for: the color of the dial is amazing. It looks so stylish and can really accessorize an outfit. The packaging of the watch was very nice and it came with tools to adjust the size of the watch. However the links color is not the best color and quality. The watch feels light but in a cheaper feel. I’ve ordered other watches from Amazon that in my opinion were nicer and felt and looked high end. I got this watch on sale for Black Friday but I’m not sure if I would pay full price for it.

Best watch for the retail price!
Color: 5885 blue dial
Ease of use:
All you have to do is put it on and it's self-winding and you never ever need to worry about batteries or winding it up! It's pretty accurate time as well and looks good! It's the best watch I've ever owned for this price and I even bought my son one for himself!

Real stainless band
Color: rose steel black dial, Color: rose steel black dial
My new favorite work watch. Wound up buying this after two failed attempts with other cheap watches from Wally world that turned my wrist black after the plating wore off in about three days. Learned my lesson. so far this thing keeps perfect time and does not turn my wrist black. Had to take a couple of links out for a perfect fit. So yeah, this will be the only brand of watch I will likely be buying from now on. Hope they’re around for a while.
Update* January 8 2026. Oh no, I had such high hopes for this watch brand BUT, I only had this watch for two months when it started dry moisture inside the crystal. No I am not a diver nor have I had the watch fully submerged. This thing is not water resistant at all. It may be great for Desert dwellers or for people who never take showers or baths with it on. Going back to my old favorite Armitron.
