Audemars Piguet
Walking The Ultra-Thin Line: The Audemars Piguet RD#2
It wasn’t displayed in a glass case for everyone to see. Instead, selected guests were offered the opportunity for a private viewing: an R&D watch, in platinum, equipped with the thinnest perpetual calendar movement ever produced.
Dubbed the RD#2 at the time, the watch looked like a Royal Oak which had gone through a successful weight loss programme. The 41mm case size was identical to the current generation perpetual calendar Royal Oak, but the total height of the case was reduced to 6.3mm. To put that into perspective, know that the recently released 41mm self-winding Royal Oak ref. 15500 has a case height of 10.4mm, the existing Royal Oak Perpetual Calendar is 9.5mm thick, and the 39mm Royal Oak “Jumbo” extra-thin comes in at 8.1mm.

Which brings us to the timepiece we have today which is essentially the RD#2 but cleaned up — and with a longer name but let’s not kid ourselves, everyone will keep calling it the AP RD#2.
I guess I wasn’t the only one who had the same two complaints I mentioned before because when the final production version of the watch came out, only two things were changed, and they are — you guessed it — the dial and material used for the watch.
