Great watch for racing

My eyesight isn’t the best at short distance so this OPTIMUM Time watch is great for reading the large font characters and has big buttons which are easy to press without actually looking at them to start, synchro with the starting gun/flags or change mode/reset.
This is my second watch of this model, the last one worked fine until the watch fell out of the wristband plastic holder……. Not really a design fault unless it had worked loose, since I had an onboard tantrum and slapped my hull……then heard a plop sound in the water alongside and realised my left wrist was just that little bit lighter, 😢

Top watch

Top watch. Does what it says on the tin. Old one wore out after around 10 years.

Christmas wish from daughter

My daughter in upper sixth put this big watch AGAIN on her Christmas wish list as she liked it so much. All her sailing friends use it too but sadly her last one is now at the bottom of the sailing lake after a challenging race. Sailing Chandlery were great to buy from too so recommend product and company.

The start line watch

This is the easy watch for the starting line.
Set it up and then try to get to the start line on time. Big buttons and the reset function make it easy to use.
Strap it onto your buoyancy aid or around your wrist or the mast.

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,
