On my mini turtle with a 4R movement when Iím changing the time slowly the hour hand doesnít rotate smoothly. It kinda skips, like itís getting stuck. It wonít move briefly then itíll move. The hands DO line up with the indices though.
I also have a skx with a 7s that does the same. All the rest of my watches the hour hand will rotate slowly as the minute hand goes around.
My my questions are what could cause this and is this something to be concerned with??
