Hi Chaplin37,
You would need a stronger mainspring than what is used in the 21J movement. It’s a good idea to identify the movement before buying a mainsping unless you can match your old spring dimensions to the one you’re considering buying. The Traveler used 1888, 1899, 1908 and the Equity 16 1/2 size movements. If your serial number is 11,000,000 or higher then it’s probably not an 1888. It doesn’t resemble the movements on page 131 in your American Watch Movements book? If not could you put a pic of it up here?
The mainspring used for the 1899, 1908 and Equity is number 2227 and it’s dimensions are 2.8-2.85 wide, 0.15-0.19 mm thick, 21 3/4-25 3/4 inches long. Note that the thickness ranges from 0.15 to 0.19. You would want to get one that’s at the stronger range. 0.18 or 0.19 since your Traveler has 7 jewels.
If possible please post a pic of your movement if it’s different than the illustrations in the book.
Please let us know what you come up with.
Happy New Year Chaplin37!
Bob
