That's exactly what I'm talking about. It was issue with old Speedmasters but shouldn't be with this one. I don't know much about it's movement either but just compare pictures below and you'll see it has potential.
This is the old Speedy where it's impossible to make good copy of it with 7750 because of the subdial spacing (although gen is handwinding but just for the comparison)
Left one is new Mark II, right one is 1969 Mark II. You can clearly see right one has the same impossible-to-rep subdial spacing but left one has the same spacing as all chrono watches we see in our rep market all of which are using 7750/7753 movements.
Just for the comparison, here is a rep Speedy with 7750 (not good one but shows what I want to point out):
I hope my observations are correct and that this watch has it's future in rep world. Fingers crossed!
