Up for sale is my Casio Tough Solar in a black case with a navy blue strap. Honestly, I've never noticed it's not just all blue until I took these pictures, and I've had the watch for about 10 years! I think it's a discontinued color variant. The world time feature is kind of cool. This is a very versatile watch.

It's been a great watch and holds a good charge, just hasn't gotten much wear in a good while. The band is intact and comfortable. I didn't see anything wrong with the crystal, either.
