SH21 winding - Crown wind back

Post by Macdaz »

Firstly apologies if this has been asked and answered already. I'm sure I've read a similar question on here or one of the Facebook groups, but I can't find it. So at the risk of repetition, here goes:

When winding my Al Deere I have noticed that as the wind is coming to the end, and you can feel the tightening in the mainspring, when I release the crown it winds itself anti-clockwise a little. Not much, no more 1/8 of a turn, but it does move back. I'm not sure if it has always done that and I haven't noticed, the PR is consistent at 5 days and the accuracy is as it always has been, well within COSC specs.

Is this normal, or is this something I need to worry about?

Thanks guys

A small amount of roll-back is perfectly normal for a handwind. See this thread here :thumbup:

THANK YOU!

I knew I’d seen it, clearly my memory is only marginally better than my search skills!
