I paid £20 for this watch and feel at that price it is good value for money. It has now gone up to nearly £50, if I'd paid that for it then I would only give it 3 stars. It might be worth paying more for it if you are going to make use of its extra features (I just want it to tell the time), but it doesn't really look like a £90 watch or even a £50 watch.
It does look a bit different with the square shape (and is in a very shiny black!) It has large, easy to read digits, and is comfortable to wear, not too big or chunky, and with sleek buttons. The only annoying thing I have found is that at the end of the strap there is a raised motif which is supposed to locate into a cutout in the retaining 'loop', which is a neat idea, but it doesn't seem to work. It does make a good 'end-stop' if you push the loop all the way past it, but it is then difficult to reverse the action when taking the watch off!
Not blingy or flashy, but a decent watch.
