I'd appreciate it if someone could give me a rough estimate on date, history? and value of this watch. The cover is detached from the watch. On the back it says "N1616" "Favre Brandt" "Patent Lever" and "LOCLE". It is silver. Thanks in advance!
Sorry, I really don't know. It's very early! Probably around the 1850s. If there is a patent number on there you can date it roughly from the Swiss patent and trademark office.
