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.

Love the OLEVS watches!!! They are all great looking and of high quality!!! You can tell as soon as you put it on your wrist that it is of high quality. The displays are gorgeous and easy to read. The ones with stainless steel straps are easy to remove links to adjust fit. If you keep your eye on the daily and lighting deals, you can catch them with great deals.
