This is a great product for the price paid. I have a number of watches including Citizen Eco-Drive right up to a $5k+ Breitling Chronomat (which costs $450.00 just to service!). For around 50 bucks this Casio offers a nice looking waterproof watch which you can wear for most sporting activities without worrying that you have the "crown jewels" strapped to your wrist.

It keeps great time and has tracked my atomic clock to the second for four days now. If I need to reset even once per week, that's still great accuracy and far better than any mechanical watch regardless of price.

The large watch (Casio divers used to be a smaller, Rolex-like, size) itself is a little heavy for the lightweight metal band to support so it does have a tendency to roll around the wrist. The only way around this is to tighten the band or replace with a leather or rubber strap. It's only a small thing and doesn't bother me too much but it shows why better designed watches can cost more; the designs tend to hold together better overall.

All that said, I've known people who have owned Casio divers for several years without issues. As long as you don't expect a Rolex/Breitling (or even Citizen/Seiko) level of design, fit and finish, I don't think you'll be disappointed with this, great value, timepiece.
