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, 😢

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.
