We do not have a detailed provenance for the ownership of this watch, so we are not selling this watch with assurance it was in possession of the renowned Sr. Mary Aquinas
aka. "The Flying Nun", however the watch manufacture date of 1919-1920 does correspond to her lifespan and we feel it is a reasonable possibility that this may have been a watch gifted to her in 1938 as per the inscription. An interesting, vintage watch in excellent+ condition, sure to be an item of curiosity for enthusiasts of early American aviation history!

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 June 30th, 2022, 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.
This watch comes complete with an appropriate, intact glass crystal; however, on request PM Time Service can replace the current crystal on this pocket watch for you. We offer a number of new and vintage crystal choices for pocket watches; you can select your desired choice from the dropdown menu below.
Please note that the average turnaround time for all pocket watch crystal replacements will be two days from the placement of the order.
with any further questions or for an estimate on any shipping delays.
Please note: if you add this watch with a crystal exchange option to your shopping cart
but later change your mind on the crystal selection type, you'll need to remove the watch from the cart in order to make a new crystal selection. Once that is done, you can return to this page and add that new combination to the cart. We apologize for the limitations to our system that prevent you making that change from the shopping cart directly.
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.
