Tough looker at a great value
Tough good looking watch. The price is great for the Bluetooth capability, being able to easily set the time and other preferences through your phone.

One of my favorite analog/digital G-Shocks. Easy to use manually or when connected to the app. Great size on the wrist, and good weight so it's not a burdensome presence on the wrist. There is a good reason the Casioak is a legend.

Can't go wrong with Casioak
GA-2100 are my favorite style watch. I know have bought 5 since January. Two from Walmart alone. They are light, durable, stylish, and inexpensive. There are a lot of options for colors. Can't go wrong with this watch, in my opinion!
