I'm looking to buy a Patek Philippe not just for my collection, but also as an investment. I've heard that some models, especially rare editions, appreciate significantly over time. But how do I know if model will truly appreciate in value and not simply become irrelevant? What criteria should I consider: age, rarity, material, complications, or something else? And is there a difference between buying new watch and a used one, which could be a historical piece?

Hello! A Patek Philippe can be a great investment, but there are a few nuances. First, rarity: limited editions or rare models usually appreciate faster. Second, complications such as chronographs, calendars, or minute repeaters are more valuable. Case material also plays role: gold and platinum are more expensive than steel. It's easier to get warranty with a new watch, while older ones can be rare, but you should carefully check the condition and documentation. The Patek Philippe watches Expertyco https://expertyco.com/catalog/patek-philippe/ offers current models with full specifications and photos—this helps you assess authenticity and compare prices. I also recommend looking at price dynamics on the secondary market, reading forums and reviews from collectors.
