Poor Quality

I bought this watch to replace a similar priced watch I purchased with Decathlon. I had to replace it as my previous one was stolen. I didn't hesitate in replacing with similar as I was very pleased with the quality and durability... but was very disappointed in comparison to the previous watch! The front marked and scratched very easily and was only used for snorkelling during a 2 week holiday. Also the watch is a 'mens' watch, but beware not much room for expanding the strap.

This product is useless - the worst purchase ever.

Those who produce and sell this product should be thoroughly ashamed of themselves. This is by far the worse product I have purchased online. The instructions are a very bad joke. Avoid buying this product and probably anything else from Decathalon.

Hi Francis,

Sorry that you have not had a good experience with this watch. I can help find a solution, please could you provide the details regarding the problems you have encountered.


Durable and easy on your eyes with reversed screen

The W500 M watch is well built with solid buttons and a design that protects the watch face from scratches with a raised edge around the screen. As someone who regularly suffers from eye strain, the reversed LCD screen means the background is reflects less light and easier to read the time, especially in low light situations.

display is useless

Buy the version without reversed display. This version is useless in ambient light, which makes using the stopwatch function tedious - because using the backlight also changed the function.

Hello Clive,

Thank you for taking the time to write a review on this watch.

If you have the receipt, I invite you to visit your local branch to exchange your watch for the W500 with the preferred screen.


this is the best watch I ever bought THANX


To replace another watch

After my last Kalenji watch strap broke, with no way to replace an all-in-one bought this together with an extra strap for later.

Great functions for the price, but...

This watch has been awesome to time runs, set timers and alarms and is really easy to get the hang of! I agree with others that after a quick play and some intuition, you won't even need the instructions, but they're clear enough if you do get stuck at all, and the display is very good too! The only reason this isn't 5 stars is the strap. It's a hard plastic that takes some getting used to, and if worn for extended periods can become a bit irritating to the skin. If it was made from a slightly softer material, this would be the perfect watch! Don't let that put you off though, for the price I firmly believe you can't get much better than this lovely piece of kit, just take it off before bed and you'll be all good!

Excellent value for money.

What does it say?

I read other peoples reviews before buying. Today I've taken delivery of the watch and I like it, with some reservation, and I will keep it. I agree with some of the criticism though. Legibility is not as good as it appears in the sales material. The strap is a piece of stiff plastic. The user instructions are very poor and I think it must be Gallic humor claiming things are 'Intuitive', because yes, you will need intuition to learn to work it. What's it worth? I've not seen a digital watch anywhere else at any price that I prefer in appearance to this one. With a decent strap and documentation it would deserve top marks.

Best Digital Alarm/Stopwatch/Timer Watch Ever!!!!!

Honestly I love this watch. I have had it 1 year and I wear it every day even when showering. I prefer a digital face but can never find attractive looking watches until this one - sleak, geometric and simple. I love the options for timers, stopwatch and an repeating daily alarm - I use these features all the time for reminders, cooking, measuring time, waking up! I use them so much I don't know what I'd do without them. The material has never irritated my skin, and has been fairly sturdy considering how much I've put it through! Could not recommend enough! Wonderful watch and for such a great price!

Great watch

This watch does what it's suppose to do, easy to set up. Using it myself. Needed one that lights in the dark

Hi Sima,

I'm sorry you found the W500 Sports Watch difficult to set up.  With the four button system used on watches it is not always intuitive to set them up. 

On the Geonaute website you have some really useful videos to help you use the watch.  The first video is setting the date and time; there's a second one on the stop watch and the third on interval training.

Hopefully this can help you get more out of the watch and help when you need to change the time. 

Kind regards,
