Okay watch
Color: Black
The SKEMI logo was not there in the picture posted but when the actual watch arrived it was there. I specifically purchased one which was advertised without the logo.
The plastic screen protector installed by default has couple of air bubbles trapped.
It works fine. It's an okay back up watch. I'm looking at different ones.

The best solar watch under $25 period..
Color: Black, Color: Black
If your looking for a watch under $25, that will NEVER need a new battery this is what you want.. This watch is well built, with its very clear negative display. The band has a quality feel and plenty of length for guys with big wrists..
For under $25 this is one you can't go wrong with, highly recommended!!

Top Notch
Color: Khaki
The size is perfect for my wrist, needed a solar watch for work in rural law enforcement, rechargeable watches weren't cutting it & frustrating when drained, so far this watch works for me, inexpensive so if damage no worries, the design is nice, the display is bright day or night so I can see it. The wrist band is a solid fit. The alarm is loud, if your looking for a work watch to save your quality watches this is for you. I recommend this watch.

Excellent value.
Color: Black
I wanted an inexpensive “work” watch so I could keep my “good” watches from getting beat up.
This one is an excellent choice…solar so no battery to replace. Bright light function for night time check. No analog function is the only downside for us old folks. Overall a bargain! 👍
