    Better than the new Ronstan

    I had a Ronstan Clear Start that died of old age. Bought a new Ronstan that was a disappointment in two ways. Did not have a 3-minute countdown option, and would not lie flat on a life jacket. This new Optimum is like the old Ronstan, meaning much better than the new Ronstan.

    good, reliable watch

    These look the same as the old Ronstan watches, but for some reason these are much more durable. I found the Ronstan eventually leaked and failed, bit I have never had a problem with these Optimum watches, except that my kids keep losing them.

    A workhorse watch that is easy to use!

    Formally known as the big blue Ronstan watch, this thing is a work horse. My last one lasted 6+ years until the battery finally died. I've since replaced it with the yellow Optimum version and still can't complain. Easy to use and navigate, chimes are easy to hear, display is easy to read and sync button is easy to find in a panic. I recommend putting on the shoulder strap of your life jacket or mounting to boom/mast as, due to it's size, it does tend to get caught in rigging at inopportune times.
