Hi guys, purchased a Longines Flagship a while ago. After it arrived I had my old watchmaker have a look and service it.
While at work he noticed the reverse wheel wasn't working and had me order a replacement, giving me the part number. The (expensive) part arrived only to be notified now that the part doesn't seem to be the correct model.
I was aware that my old Russian watchmaker wasn't very good but I was a bit hopefull.

If I understand correctly the faulty reverse wheel only charges the spring in one direction.
I must admit I never noticed there was anything wrong with it in the first place.

Any chance someone can refer me to someone who can have a look and if needed fix it for a fair price.
