September 2017, I have a Zenith pocket watch in for overhaul. It is fitted with a Zenith Manufacture Caliber 19 NV for pocket watches with 15 jewels. The dial is from the seller "Petter Nilssen, Lillehammer". The watch needs a cleaning and a new glas and the set spring seems a bit week, it looks as someone has worked on this problem before. The watch was a confirmation present given in 1914 by the parents to their son which became a farmer and used the watch on a daily basis until 1980!
