The watch I bought for £180 (?250) on Groupon UK in May 2015, has STOPPED working. When the watch was delivered, the glass of the watch box was broken, but I did not want to make a complaint about that. But I am extremely disappointed that my watch which says 'Made in Germany', to have stopped working after two months! 
Description of the defect: Three weeks ago (29.07.2015) the pointers had stopped working in the morning and the crown seemed to become 'blocked' and would not turn clockwise. After a few tries, the crown became unblocked and the pointers started working again. 
Then, the same thing happened one week ago (07.08.2015) where the pointers had stopped working and one of the two small mechanisms (the one which is below the writing ?Germany?, stopped working. I tried adjusting it with the crown again, and it started working again. 
Then two days ago (11.08.2015), the watch stopped working again and the pointers and the mechanism on the right did not function. I tried adjusting it with the crown, but this is blocked when you try and turn it clockwise. I have tried and tried but nothing happens. 
I am very disappointed to have been sold a faulty watch. I had hoped I would have this watch for 10-15 years before I faced any problems, not 2 months! 
I hope an acceptable resolution is found to this problem and I hope not to face any problems with the watch. 
I will be posting the watch and will send photos of the watch and guarantee. I will also post the watch with recorded and signed delivery to ensure it arrives to you.
