I prefer the 5130 case over the 5230 as the former in my eyes is pretty unique in the PP case line-up with its lovely rounded forms. 5230 case is more like “standard” case design of PP which can be found in pretty similar versions on other models.
But as I already own a 5130G and I strongly dislike the fonts of the 5131 and even more strongly dislike the engraving on the bezel the 5131 is not my cup of tea.
The near future will most probably bring us a 5231R and this is the model I’m waiting for when it comes to enamel dials.
From another collector in Germany I’ve heard the following story: a friend of him has ordered a 5231J and got it from his AD. The friend was not at all happy with the execution of the enamel dial as it was blurry and colour wise undistinctive. He refused the watch and his AD talked to PP in order to get another piece. But after delivery of the second watch the friend claimed the same low quality of the dial and refused to buy again. Dials of both watches were in much lover quality than on 5131 or other 5231J displayed on the PP website.
This is just a story that I was told and I did not see the watches or any pics of the dials. I would be interested if any of you guys have experienced or heard of a similar issue.
