A workhorse watch that is easy to use!Review by Staff Review
Quality
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.
