## Description

Casio Sports Watch GA-2100-1A2ER

Review: Bulletproof - This is my daily driver watch that goes with everything. It has been used and abused and still looks incredible.
Review: Love The Options - Pros: Fits my 7-1/4" (7.25" / 184mm circumference) wrist quite comfortably with plenty of adjustment. I like the octagonal bezel with many different options of color and and dial. I enjoy the various modes it offers. It's nice being able to see UTC time and have timers as well as alarms. Since it's quartz/battery driven, I like not having to wind it or often adjusting the time compared to mechanical watches. Cons: I wish the hour and minute hand had a brighter luminescence but the on board light helps in the dark. It's also difficult to read the screen from 17min to 25min. Even worse from 3:17 to 3:25 when both the hour and minute hand are blocking the LCD screen. Overall: I love the watch. It has its minor issues but it wouldn't deter me.
