You are bidding on an antique Zenith (Swiss) open-faced pocket watch, probably ca. early 1900s. This watch measures approximately 52mm (2″) diameter, which is roughly equivalent to a 16-size American pocket watch. This watch features a solid silver hinged-back-and-bezel case, a 15-jewel stem-wind stem-set movement, and a single-sunk porcelain dial with fancy script numerals and gold filigree hands. I am not sure of the exact silver content. The case has the French silver hallmark of the swan with a P next to it, which I believe stands for sterling silver. The case is in very good condition, showing signs of normal pocket carry. The dial is in excellent condition, showing no visible cracks or chips. I serviced the movement in August 2018, and it runs and keeps excellent time. I also installed a new/old stock glass crystal. Overall, a very presentable watch that is ready to carry with pride. You can own this very high grade, super clean Swiss-made pocket watch, for $399.99. If you have questions about this watch or about my watch and clock repair services, please feel free to contact me.
