My order number is T42349-. The watch stops even fully wound when put flat on the table. It normally works well on the wrist, but it very often stops when laid flat. Most recently the watch has also stopped when wearing it, even if the watch has just been wound. 

The watch has been handled delicately and it has not been dropped or damaged in any way.
