The Patek Philippe Perpetual Calendar 3448 is one of the most sought after and beautiful vintage Patek Philippe watches. This example has perhaps the finest case condition we have ever seen. The case is sharp and very clean, with deep, pronounced hallmarks. We do not believe this watch has ever been polished. The dial on this watch has a few small blemishes near 1 oclock; but besides that is very clean and entirely original. With these watches regularly selling for close to $200k, this example offers phenomenal value.
