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 June 2025 and is in good working order.

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