·In the UK, where I believe the OP is from, very few ADs have watchmakers on staff so this is the most likely scenario I would think. AD simply cannot buy the part and the only option they could present to the OP is to send in for official service. Obviously OP can confirm.
As suggested, I very much doubt the AD has a watchmaker onsite, and from whats been said I suspect even that wouldn't remedy my issue.
Time to make some calls and see if Cousins or Otto can help.
Thanks again
