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!!!!!
Used for More than 1 year
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

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,

Useful, Modern Sporty, High Clarity LCD Watch
Used for 3 to 6 months
This is my daily watch which i use for all activities where potential damage might be an issue. Also, most usefully, i use the timer function when at my desk to remind me after 30 mins sitting to stand up/move around for 2 mins etc before another 30 mins sitting etc - all day i'm alerted to this - most handy. I have the grey color. I especially like the LCD clarity - very clear characters which can be seen at very low angles without the other circuits/characters showing - very modern bold characters as well. Not a fan of the interchangeable watch straps because under some operations in using the buttons it's possible to slightly dislodge the strap - easily pushed back but a little annoying. This new color version appears to have the buttons slightly raised compared to my Grey / Orange watch which i have to purposefully and intentionally 'find' causing a slight but transient irritation. Overall though, very happy, very useful watch. Love this new blue color!
