Defective TAG Heuer

I bought an expensive Tag Heuer watch for my husband in December 2019. Within the first month, it was sent to Picot and Moss (via the jewelry store) for repair because the watch was losing a lot of time. We were very disappointed in Tag Heuer. The watch was returned after 4 weeks. The watch was then still losing time and inaccurate so my husband took the watch himself to Picot and Moss and waited for the watch whilst the technicians made an adjustment to the watch - apparently this visit was not recorded. In 2021, this watch fell from the bedside table and stopped working and was again sent to Picot and Moss via a jewelry store. We were informed that a spare part had to be imported and it took nearly 3 months for this watch to be returned to us in May 2021. In early December 2021, my husband was shocked when he realised that the adjustable knob of the watch was missing. Yesterday 11 January 2022, this watch was again taken to Picot and Moss for repair and we are still awaiting for their assessment as to why the knob came loose. We have not yet received the promised e- mail from them as proof of submission of the watch to them. We are very disappointed in the durability of Tag Heuer. It is unacceptable that a brand like Tag Heuer has manufactured a watch with so many defects.
