Best sailing watch
Definitely THE best sailing watch for racing dinghies/hobies etc.
User
Brilliant
You may read a few reviews from one or two miserable people by ignore, this is arguably the world's number one dinghy racing watch and my last one lasted 12 years before I sadly dropped it overboard by mistake. Over half the dinghy racers in my club and nearly two thirds of the sailors in this year's worlds wore this watch. It's brilliant! 😃

qualité au top
Chrono parfait pour les sports nautiques, facile à prendre en main et assez gros pour lire quand on bouge

Ottimo
Ottimo orologio da regata, display e tasti ben visibili anche nei momenti più movimentati a bordo.

Strap is too short and clasp is flimsy.
The unit itself works just fine, however the supplied strap is far too short to wear over foul weather gear and the buckle broke after only 2 wearings. Optimum's response was that they don't see that breakage often and that I could buy myself a new strap and buckle. Not a great response, plus shipping to Canada would at least double the cost of the strap.I have made my own replacement!
