Tempo Watch poor quality

I bought my son a Tempo watch at the end of May 2018 for his birthday at Amrican Swiaa at The Grove. I used to wear one for years many years ago. But, this watch has had it's numbers come loose 3 times now... after the first time it came back from repairs, I wore it for a few days before I managed to give it to my son, and some of the numbers came loose again. The watch is in again for repairs with the 6 having lost it's digit. Surely if the watch is having so many problems, then they must be taken off the market; I hear it is a frequent problem talking to various other people.
