Seiko 5 Automatic 21 Jewels SNK621 SNK621K1 SNK621K Men's WatchSeiko 5 Automatic 21 Jewels SNK621 SNK621K1 SNK621K Men's Watch This one is famous for its long term accuracy; an excellent aggregate drift of 13 seconds every month. Plenty hard case, its even, attractive and dont scratch too easily. So is the Hardlex crystal glass. The lumes are efficient, if not outstanding. Its the even laying that does it and the 7S26 caliber needs just a couple of twirls to be initially charged after a prolonged resting period.

Comfortable and bright glow!
Color: Khaki, Color: Khaki
I've had this watch for about a year and never take it off. The glow feature is so bright it will light up a dark room and blind you if you just woke up 😆. But I love it. I trimmed the strap to just fit cause it was a little long.

Very inexpensive looks nice solar holds up the light extremely bright for what the cost is it's nice does it compared to Casio solar no but it's well worth the price for what you're getting.

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!!
