As one who owns the Calatrava with these set of complications.
The last of its iterations.
Just the bare essentials: seconds, dates, power reserve and moon phase.
Discontinuing these with the 5055 elevated the Calatrava and the Nautilus at the same time.
To own this complication, it's the 5055 or the 5712 now.
A genius move by Patek.
2,850 Patek Philippe listings are live on the eBay market and 1721 collector listings on the WatchProSite marketplace.
