Highly recommended!
Highly recommended! Good quality, clear screen, waterproof, floats in the water, comfortable strap. Downsides are that friends at the sailing club say that they have had ones that have popped out of case and sunk, so they put tape from the edge of watch to hold it to the case - but I haven't found this problem and been getting perfect starts in the races since using this watch! A must get.

Broken not working
My son kitefoils for the GB team and his coach said he needed one of these watches. We took it to the world championships in Italy and it didn’t work. Such a nightmare and now too late to return now we’re home. So having to buy a new one. Hopefully this one will work.

I use the watch for kite foil racing. I love how big the numbers are so easy to read with sunglasses on while being sprayed with water, also I use reading glasses normally so the big display really helps. The buttons are big and easy to operate despite all the chaos going around me at the start. Plus the audible beeps in the final minute tell me when the start is without looking. This watch nails it. Pricey though.

Does not seem brand new. Scratch and scuff marks are clearly visible on the watch.

I like the watch a kit. Large display, easy to read and operate. My only criticism is that the alarm is not kiud enough. I could gear my last one well, but this one I have to hold to my ear to hear.
