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.
The diameter is 45mm, which is a little smaller than usual, and is a size that is familiar to Japanese people with smaller hands. The overhaul history is unknown, but the balance is in good condition and ticks nicely.

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