First, congratulations with your fine IWC Schaffhausen watch.
Than what i wrote as titel, the similarities.
What you did with your IWC Schaffhausen, i am waiting the moment the right Rolex, type, color, comes bye to catch when all check boxes colored green.
I began in 2002 so for 21 years the proces is going on.
Status: I start with the Airking, than the Oyster quartz, shifting to Millgaus, than Cellini, and the last years i bumping on Date Just and Submariner.
Sure the YM is a strong candidate too.
Much pleasure with your long waited all check boxes colored IWC Schaffhausen.
