Ice-Watch - ICE star White Silver - Women's Wristwatch with Silicon Strap

I was pleased with my 2014 ICE watch but it needed upgrading, so I was treated to this one.Looks great, but I can't get it to work! I did not get any instructions inside the box (which was such a challenge to open in order to even get the watch out!, my partner struggled too), so I have a new watch that I can't use until I have worked out how to get it to work!I have looked at their website but there's no advice there, so I will continue Googling until I can find out how to spring it into action so that I can actually wear it.Happy, but not happy.
