Have a strange problem with a 2836 clone , Had the movment out and when i fitted it back thought i had dislodged the keyless as the time set position didnt work just span with no resistance. So stripped and reset it but still the same , By chance I pulled the stem a bit more and it clicked and would set the time , Its as though the time set position isnt engaging unless you really pull the crown hard out , it works but not ideal but cannot see what would cause this , anyone had this before ? Im sure I had the same in the past and was forced to leave it like that.
