5960P-016 (black dial), Yegor.
The 5960-family is an important part of Patek's history because it features their first ever self-winding chronograph developed and manufactured in-house (caliber CH 28-520 IRM QA 24H), which was unveiled to the public for the first time in 5960P-001 (gray dial) nine years ago. However, it also features an annual calendar, which in fact was patented by Patek in 1996. In other words it offers both history and useful complications. The former can't be said for the 5905 IMHO.
But why would you pick a 5960P-016, Ouroboros? It had a short run production of just one year (2013-2014), which most likely will affect its value retention, but also due to the monochromatic ''theme''.
