I have no reason to believe you have bad intentions or are defrauding anyone.
However, since this is the internet, I also have no evidence that any of your claims are true, nor do I personally have any experience or evidence that you are a
good / reliable watchmaker. For all I know, in real life, you might be a Nigerian prince sitting in an internet café in Lagos
Although I want to assume best intentions on all sides, the matter remains:
what you and @Minome are claiming cannot both be true at once, so (at least) one of you is either lying, obfuscating, or misremembering things.
One person here who I
do trust blindly is Trip
@tripdog - and if he says he sees things like plating being removed from the hands and brass being visible, that didn't happen by itself, someone had to take the effort to do it.
@fixwatch.co.uk for what it's worth, as one man's non-binding opinion:
I would say it at least makes sense to offer @Minome some kind of refund. Even if he's not being truthful and you are, it's a good way to safeguard your future reputation here. Especially as far as I see, the only cost to you is your time. And yes, in the future, it might make sense to create a bit more of a record of how you receive and send back a watch so there's less opportunity for situations like this one.
