Very poor watch
This is a waste of money and time ordering it. The watch turned up loose in jiffy bag with no instruction manual, guarantee.....and the watch strap was damaged and aged, so was the watch screen and it didn't even work (unable to use the buttons). Refund quested straight away.

Failed after two weeks
Received the watch. It looked very well made and was really good for sailing with the race countdown feature. After three outings, moisture started to appear under the watch face. Some of The digital segments started to disappear. Eventually there were only four random segments lit. I was very disappointed so returned for refund.

A dead battery with only 7 months...
I bought this Optimum Time Series 11 Ltd Edition Sailing Yachting and Dinghy PINK watch on an order placed on December 7, 2024 and unfortunately today June 8, 2025 my daughter sent me that photo where it appears as a dead battery with only 7 months...

Utterly Useless When Wet
I'm going to start with the positives. The pre-programmed countdown function works really well, the moulded rubbery strap isn't the worst in the world and not uncomfortable, but has the potential to break off once its aged a bit... However, it'll never age because the watch will give up long before the strap decides it can't cope anymore. As the title suggests, this watch is useless when it gets wet, a bit of a problem for a watch advertised as a sailing watch. If you never plan on going afloat, but need a watch with a decent display and countdown function, then you'll be fine; however, at the first sign of a wave, the screen fogged up and some of the digits stopped displaying. After two days of careful drying out, the fog cleared to leave no digits displaying at all. It was dead. I have given this 1 star, as I simply couldn't give any less. This is a hopeless watch for those who sail on water. It may be better suited to radio sailors or land-yachters, but if you plan on actually getting wet buy a Casio or Timex instead, you're money will be much better spent!
