This may look like a simple steel watch, but it’s actually worth over $150,000. The same hidden details could be in your watch box.

We go deep into the world of vintage Patek Philippe Calatravas to reveal why seemingly identical watches can vary in price by over $100,000. From the rarity of stainless steel over gold to the "cherry on top" of a Tiffany & Co. retailer signature, we break down the three critical factors - Material, Details, and Signatures - that turn a nice vintage watch into a high-value collectible asset.
