First I like the warm Patina of the dial of the RG.
Second - for me - the date and month windows of the RG harmonize more with the dial.
Third 40K more (CHF, $ or €?) are a lot of money. If your heart really beats more for the PT than it is worth
the price difference, if not you could spare funds.
Personally I would try to see the PT in metal before pulling the trigger.
Just my 2c.
Best, Thomas
