Quick Q for the technical folk.

I have a Hamilton Khaki Mechanical, about three years old so out of warranty.

It doesn’t wind. If you turn the crown, it moves with no resistance or sound etc.

My thoughts are that, if it needed a full service, it isn’t worth it given cost vs sourcing a replacement.

However, if it’s just the stem or something similar, is it easy and cheap to fix and who would you recommend?
