Airbubba...
Many thanks. I'm getting the watch back from my indie local jewellers tomorrow and will try the steps you outline. If no-go I will try Anayda's suggestion.
I bought the aerospace second user 6 years ago from a reputable re-seller with original box and papers, including pre-purchase overhaul and new glass and bezel. I also have a Colt...purely mechanical* and Golds****s have sent that off to Breitling for 3 battery changes during its 17 year life...never a query re service and it still keeps perfect time.
edit: * of course I meant analogue!
