Biggest congrats for this acquisition π. The G -001 has surely got a very beautiful dial (for me the most beautiful of all G). If you have a wrist for the 41 mm case, and you surely have as we can see on your pics, the 5270 is a wonderful and easy wearing watch.
I own 3970 and 5270. Both designs are each of its own and not really comparable. So is the 5970. All 3 models cannot replace the other but represent a period of PP history. This is what is making me love collecting PP watches.
I fear, one day I have to look out for a 5970 too π±
