Incoming - Audemars Piguet 15407ST Openworks
Very happy to finally land this super rare and hard to get AP Openworks 15407ST in Stainless Steel.
The 41mm SS AP Royal Oak Openworks features several improvements over the older 15305 version. It has a gold bridge across the balance wheel and there are two balance wheel ( supposedly this improve accuracy ). The overall effect is that it gives the watch a very "tourbillon" feel.
Here are some pics
