I bought this watch to replace my expensive metal watch as a trendy "summer" alternative. It arrived well packaged, telling the correct time (always a good start), and despite other reviews saying it has a large face, it is actually quite modest.
I am a 20 year old with very skinny wrists (it's all this typing), and as expected I have to fasten the watch very tightly - to the second tightest setting/hole, in fact.
As Swatch watches pivot either side of the face, there is a slight "corner" effect that goes on for me with my skinny wrist. What I mean by this is that rather than there being a gentle curve around my wrist, the strap pretty much goes perpendicular from the edge of the face to the side of my wrist.
However on a normal sized wrist this should not be an issue.
It also ticks VERY loudly (true across all Swatch watches apparently). My partner (an avid watch collector) has proclaimed that it is the loudest tick he has ever heard, even on a Swatch. So there you go. Perhaps go for another brand if this bothers you, particularly in bed.
There is also no date display, which is sometimes a bug if you're used to one.
Other than the above, it looks great, is very easy to read (even with my terrible eyesight) and seems as accurate as a watch can be. It's also "splashproof", which I suppose is standard in watches these days. Not sure how it copes submerged in water however; I would not recommend trying!
