Thanks glad you like it. I’ve been meaning to sort this for ages!
the one that fell off measured around 4.5mm and was far too tall. I think about half that would be more in keeping.
is there a different between crystal and acrylic?
Well done on getting as far as you have, your positional errors may be down to worn jewels, pocket watches are by their very nature and design run in pendant up more than any other position. So other positions may have pivots running on jewels that are slightly out of round .
