Thanks for the input. The case, hands, crystal and crown/tube are all genuine.
Yes the crown/tube is the 702.
Yes the dial is a big mess and yes, there was no collaboration between Tudor and Blancpain.
This watch is being cobbled together by my watchmaker, for my watchmaker.
I ordered a beezel from Clark and I have a Rivet bracelet I bought from 'nuq (I think) but it needs the end pieces.
I think we will try to get the blue snowflake dial and blue insert.
Then, perhaps a trip to The Zigmeister to match the lume on the dial and hands.
