Sent last year for a battery change. Watch returned working but after a few weeks stopped. Returned watch and was informed that the new vastly improved batteries they were using had an issue with the mechanism of my watch. (Mine cannot be the only one). I agreed to have the watch overhauled. Having not heard anything from them for months, I enquired if my watch had been lost. I was informed it hadn't but that it had to be sent to Cartier. I should have been informed of this. In May 2023, a reply to my email concerning whereabouts of my watch, I was informed, that I would be contacted when they had any information. I have repeatedly emailed and used WhatsApp to contact them but they do not have the decency to reply. I am wondering if my watch is lost.
