Look, from a fastidious collectors point of view, it is a bit rubbish. But it is correct rubbish. Indeed, it is original rubbish.
In fact to me it's not rubbish at all, as long as it's cheap. It has correct parts, it's a bit polished on the case back, the bezel is very damaged, but it's correct. The dial may actually be pretty good - and that is the one thing that holds the heart of the value and attraction. Be careful, I cannot tell if the dust spots are that, dust, or spots of damage on the dial, which would dampen my enthusiasm, and make me want it cheaper.
I can find pleasure in almost any speedmaster if the price is low enough to balance out the problems.
This watches problems are that of condition, not authenticity and originality. (Which is a positive)
Owning such a watch, at the right price, will teach its owner far more than trawling the internet.
