I am very please with 3951 EVO watch. I am very please with the quality, visability at a glance, durability and the velcro strap. This watch works very well for me as I am a motor grader operator and I need to be able to document times at a glance. The large numbers and hands are very easy to read in any condition of light or dark. The time has not missed a second from the day that I bought it.
