I read a number of reviews slating this watch before I bought it, mainly due to it's "lack of functionality", "lack of a stopwatch" and it "not being a sports watch". A lot of the points made are perfectly valid but obviously the people buying it didn't bother to read any sort of spec before doing so.
It is lightweight, comfortable, can be worn whilst doing most sports but ONLY tells the time. Technically it does have a date setting too, but to change the display you need to push in a tiny button at the back of the watch with a pen, so I almost certainly will never use it (this is the reason it got 4 stars an not 5)
I'm a P.E teacher and wear it during lessons to keep track of time and it's perfect for that. If I'm doing anthing that requires a stopwatch - I get one!
Best advice is, before buying this watch ,decide what you want it for and whether it fits the bill!
