The 15300 is my favourite AP much prefer it to the 15202, screw in crown and date-change feature to name but a few. I have had 3 over the years and it was only due to the values a couple of years ago that I sold it. I simply couldn't justify having that much value in one watch and on my wrist, I wore it on a week long trip with family to London just after the Pandemic and remember feeling very uncomfortable. Similar to what happened when I had my PP 5167 and wore it on holiday in Ibiza.
The first one I bought was brand new from the dealer and was £6750, which compared to a Rolex SD at about £2500 was nearly 3 times the cost but still quite acceptable IMO. I sold my last one to Watchfinder, probably just at the peak of the madness. They gave me £38,000 for it!
I'd have one back if they ever dropped back to the sub £20k region. Fabulous watch, remember condition is key with they case and bracelet. They will only take a few polishes and replacements are mega money. The pics you have included look like the bezel has been brushed with the wrong grade paper. Not seen such defined brushing on a bezel before, maybe an independent job?! Hard to say without seeing first hand.
