We would like to introduce pocket watches from JUNGHANS, a German watch manufacturer founded in 1861.

This is a gold-plated hunter case mechanical pocket watch from around 1930.
The dial has the word "ESTRELLA" written on it, and the message "CHAMPAGNE MONOPOLE HEIDSIECK CIA. REIMS" is engraved on the back of the case, which appears to be a reference to the famous wine brand "Heidsieck Monopole" from the Champagne region of France.

It was overhauled in Japan in May 2024 and is in good working order.

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