We will introduce pocket watches from Patek Philippe, a Swiss company founded in 1839.

Patek Philippe is considered one of the world's three largest luxury watch manufacturers, along with Vacheron Constantin and Audemars Piguet, and is a manufacturer that is synonymous with luxury watches and stands out among them.

This is a pocket watch with an open face case made of solid 18k gold from around 1918.
The back cover has a simple design with no engravings, and there is a hallmark on the back cover and inside the inner cover guaranteeing Swiss 18K gold.
The inner lid is engraved with a message stating that it was donated on January 18, 1918.
The dial is metallic silver in color and features an elaborate double-sunk design with the center and small seconds recessed in two stages.
It was just overhauled in Spain in June 2025 and is in good working order.

We hope this once-in-a-lifetime encounter will be a special one for you!
