At 40.5 mm, this MR shouts for attention, not your understated Patek. Sorry to see PP is going for larger diameters big time. This must be the TS effect, since HS is retired. FYI, I had a chance to examine and wore 5159G on many occasions. The very busy dial and the 39 mm diameter case was no go for me. The forced fit of the 5059 mechanism to a larger 5159 case also looked tentative. The design of the 5213 looks even worse due to the disproportionately small day and month windows and the larger Arabic numerals just to fill the larger dial/case. I still think of 5050 as the best pc-retrograde which is also very understated. Personally, 38 mm is the maximum diameter for me - anthing larger looks too chunky and fashion jewelery. Cheers. Jim
