Have a stainless Tank purchased in 2012. Has had a "full service" at least 1x, if not 2x, as well as battery replacements. I used to wear it daily, but have been wearing an Apple Watch in recent years instead. Saw that it had stopped, brought it to the boutique and they recommended a full service, which I agreed to. (They then followed up and added on a replacement crystal.) Went to wear the watch for the first time since it had been services - and it was no longer keeping time (though not completely stopped). Contacted the SA who had handled my repair and she didn't give me much, other than instructing me to bring it back in (or to send it in). I'll go this weekend, but has anyone else experienced this - and how did Cartier handle? Frustrated by the whole thing!
