Yeah I've been following this with interest. I used to have the seventies chronograph reissue and airways regretted selling it as the process went bonkers after. I suspect this one will be out of my reach but it's a lovely thing. Nice that you get a solid back aswell if exhibition isn't your thing and prefer to keep it more authentic. I think you receive both casebacks.
Will be very interested to see price. My guess is either £1,750 or £1,995. Either of which would certainly put it out of my reach.
