Instant purchase is welcome. This item belonged to my great-uncle (born in 1918, passed away in 1994). Based on my great-uncle's records, I believe this was made from the late 19th century to the early to mid-20th century. The acquisition method is unknown as it was not recorded. After various investigations, it was found that 19 jewels (19 rubies) are used in the internal parts, and the silver content is 800/1000 (see photo 2). Please understand that the long hand is missing and the operation has not been confirmed.
