[OHNE G-Nachweis]
I had previously sent back this watch to be repaired, unfortunately I am not sure whether the problem was resolved or not. It was posted back to me without any details of the fault or details of fixes if any. 

I am now sending this watch for the second times, there are two problems.
1.   It constantly falls behind, since I bought this watch it has never been correct. It?s extremely unreliable, I am now having to check the time on my iPhone instead of this watch.  
2.  The other problem is that a part of the watch has come loose, it?s clearly visible from the back of the watch.
 

I would like ask for refund please, it?s too unreliable and expensive each time I am sending for repairing.
