wow! Thank you so much for these additional informations. Love it. I didn’t know the High Time article.
You might think I'm crazy, but if this really is going to be my anniversary watch, then I could imagine having the rotor replaced or even custom-made. I have a good friend who owns almost all the watches from the 5159 series, and he even had the hands replaced on one of them to improve readability (I think it was the G).
I have no idea what it would cost to replace the rotor. Probably a fortune…
Of course, all of this should remain at least somewhat economically reasonable.
