Who knows the validity of the sellers claims, i'm sure i've seen this one up for sale before so the link to the story is perhaps getting a bit stretched. it strikes me you have a perfect bracelet and case (assuming it has a case number and the case number makes some sense)
movement from an unknown source (what is the bridge signed), a main hand set from a blue dial Montreal, wrong colour sub dial hands and an odd fume dial, intended for some other watch, that has had 'Heuer' applied to it.

should you happen to have a spare dial and hands it could be returned to 'original'
