In both references are the ref and serial engraved in the case back?
Aren't these models prone to vanish those marks, as the engraving is very lightly done?
Honestly beside the chrono hand I could not see big differences in both dials,
Can you please give me some lights here, and also what details to look when trying to source one? Beside polishing and dial condition?
Thanks
and dont forget the 22704-1...larger brother to the 22705-1 also with v72, but the earlier v72.6
