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.
We do have a professional watchmaker that does all of our cleaning and repair work for us. To have your watch serviced before shipping, simply add this Cleaning/Service Agreement
to your shopping basket. The cleaning and timing service is $95, and depending on the time of the year, has a turnaround time of 1 to 3 weeks.
Please note that we provide this service in addition to the listed purchase price of our watches. If you do purchase this option and later decide to return the watch, this fee is non-refundable.
This watch comes complete with an appropriate, intact plastic crystal; however, on request PM Time Service can replace the current crystal on this wrist watch for you. We offer new plastic crystals for most vintage wrist watches; you can select your desired choice from the dropdown menu below.
Please note that the average turnaround time for wrist watch crystal replacements will be two days from the placement of the order; however, we do not carry every model of crystal in stock and there may be a delay of up to seven business days as we order the correct item from our supplier.
for 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.
