I have a couple of watches with 9015s. One the them has started to have about a half turn of backlash in the crown when setting the time. Is this normal or is something slipping? Otherwise all seems well.

Not winding, but when the crown is fully extended for time setting it's started to have a half turn backlash, which it didn't have before. Just wondering if it's a trait of the 9015. The other watch I have with a 9015 has no backlash in the time setting.Originally Posted by higham5
I've got about 3 or 4 with the 9015 in and nothing when setting the time with any of them.
So I guess something is beginning to fail. Somehow the winding stem is not engaging correctly with the hands.
So are you turning the crown without it moving the hands?
Can you take the back off, has the stem come loose from the movement?
The crown has about half a turn of backlash, ie there is half a turn between moving the hands forward or back where the crown is not engaging. Don't want to take the back off because I'm not sussed enough to know what could be wrong and I would risk disturbing the seal for no reason.

Is the crown loose on the stem?
It does not appear to be. Just realised that sometimes it's OK, but mostly there is this backlash. Not particularly bothered because I can still set the hands. Just intrigued as to what would be the cause. If it gets to the point of not being able to set the time, then I will have to get it fixed.
Fingers crossed then if it gets to that point it turns out to be nothing.
No fault on anything is unique. I'm sure backlash on the time setting function has happened to other watches. Maybe one of our resident watch engineers has come across it and knows what the possible cause(s) are.
