100% functional watch
Light is subpar , but a 100% functional. Digits size is fine (I am 60). Labels could be brighter, but Casio rarely does modifications to these models. My dad has the same model, now over 15 years.

Great watch.
Great watch, I mean it’s a Casio so that’s not exactly a hard sell but it looks great if this is your style of watch. I have “a few” watches and about 30 Casios this one is a fun design with a lot of functionality.

Solid, durable watch
This is a solid add to my collection. Casio doesn't make a bad watch, this AE-2000W-1AVCF has all the functionality and durability we've come to expect from Casio. Easy recommendation, especially at this price.

Casio for the Win
I have the Casio W-218 (which is still kicking) and wanted an upgrade. This model has everything I need; full date, more water resistance, mineral glass, and is aesthetically pleasing. The 10 Year Battery is an added bonus. Like most Casio watches this one is easy to set up and use. Fits great on the wrist and functions very well. I plan on buying a replacement strap eventually but I expect no issues from the watch itself.
