We would like to introduce a pocket watch from JWBenson, a watch manufacturer that is a purveyor to the British royal family.
Benson is a watch manufacturer founded in England in 1840, and is a very popular brand in Japan, known for being used by Jiro Shirasu and others.
[Brand introduction] JW Benson

This is an open-face pocket watch with a sterling silver case, and the engraving on the case indicates that it was made in 1901.
The movement is a British hand-wound "BANK".
The Benson with its cursive logo is very popular, and it is a simple and solid watch that is very typical of a British watch.
The overhaul history is unknown, but the balance swings well and is moving smoothly and energetically.


We hope this wonderful antique watch will add color to your everyday life!
