Introducing the gold pocket watch from JE Caldwell & Co and Vacheron Constantin.

This beautiful pocket watch from circa 1915 features a solid 14-karat gold case and a pure white dial.
It was commissioned by Vacheron Constantin, one of the world's three largest luxury watch manufacturers, to be made by J.E. Caldwell & Co., a long-established luxury jeweler in Philadelphia, USA.
The dial and case are stamped "JE Caldwell & Co", and the movement is stamped both "JE Caldwell & Co" and "Vacheron Constantin".
The movement uses wolf tooth gears, which are synonymous with high-end watches.
It is a slightly smaller size with a diameter of 45 mm, which is a comfortable size for Japanese people with smaller hands.

It is unknown whether it has been overhauled, but the balance wheel is in good condition and ticks along smoothly.

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