The Hamilton watch company began business in Lancaster, Pennsylvania in 1892 and still operates today. The last watches produced in the American factory were made in 1969, after which the company was sold to a Swiss owner.
We also offer a collection of reference and research books for a number of different watch manufacturers, which can be found in our
Watch-Related Books section. As an additional resource, we've posted a
Serial Number Production List which includes information for Hamilton serial numbers and dates of manufacture.
The NAWCC also has a
comprehensive article about the company; additional information may also be found on
Wikipedia.
You may browse all of our men's pocket watches from this manufacturer at our
Vintage Men's Hamilton Pocket Watches category.
This watch is in good running condition, unless otherwise noted in the description. This means that on receipt, pending any item-specific running conditions noted in the description, you can expect the watch to be winding and setting properly and to run smoothly while keeping reasonable time. We consider "reasonable time" to meet these basic guidelines:
- Railroad Grade Watches will be keeping +/- 5 minutes per day
- Pocket and Wrist Watches with 15 or more jewels will be keeping +/- 10 minutes per day
- All key wind watches and watches with 14 or fewer jewels will be keeping +/- 15 minutes per day
The above guideline is the lowest standard in which we would ship out a watch, however in most cases, you will see much better timekeeping. Most of our watches have been in storage for many years, so if you plan on carrying/wearing them everyday, you should consider having them cleaned and oiled soon, and then once a year thereafter to keep them in top running condition. If the watches will be for occasional use or display, they should be cleaned and serviced every 3 to 5 years depending on use.
As of October 30th, 2025, we are not offering a cleaning and service option through PM Time Service. While we do hope to offer this again in the future, we are unfortunately unable to meet customer requests for watch servicing at this time. Please note that, unless otherwise mentioned within the "Full Description" tab, this watch is being sold in good running condition and is ready to wear or carry on arrival.
Unlike modern quartz watches, most vintage watches need daily winding in order to keep the watch functioning for timekeeping. Additionally, there are a number of different ways to set the time other than simply pulling the crown away from the watch body. We are happy to provide an overview of each of the different setting types on our
"How To Use" page, where we also provide information on proper winding techniques for each style and some suggestions for the proper long term care and storage of your watch.
For your gift giving convenience, please find a consolidated overview of the information on this item, with no reference to the price, on this
printer-optimized page.
