Optimum time OS timer.

I use this timer when I am racing my land yacht (which I have been doing for 70 years) and I find it easy to use and highly visible. I have purchased from Sailing Chandlery and find them very good to deal with and am very satisfied with their service,

An excellent sailing watch, easy to use, easy to see from a distance and long lasting. We have ours on the boom of the boat so we can both see the countdown.
