This Casio F-105W accompanied me to all my sporting outlets from March 2011 to sept.2013. I appreciated its light weight 22 grams, simplicity, readability of his time. In swimming it is completely waterproof (to -2 meters). The rubber strap is comfortable, does not sweat like plastic, and its life was 2 ½ years. The cost of replacing it is close to the price of the watch, I have not hesitated to buy a CASIO.
