there was another similar thread of trading a 5711 for 5070.
I think now people are starting to realize “value”.
However, if that’s my only Nautilus and now that’s it’s discontinued, I will be hesitant unless maybe I swap for another PP Grand complication like 5270G/ or R.
Really depends on how much you like those 2 watches.
Good luck with your decision...but I think you’ll miss your Nautilus.
If you’re lucky, when prices started to be less crazy, you can always get it but locked in “profits” for now. That being said, the Gronefeld is not up there yet.
