I hope someone can help me on this. I have a Waltham 14s Bond St. Model 1884 made in 1886, I need a main spring and being a newbe I don't have a parts manual yet. Can anyone give me a number so I don't order the wrong one. Thank you. Jim

Hello Jim,

The factory parts # 2211 should be the one you are after for a 14sz Waltham Model 1884

Thanks a million This really helps. I really don't like guessing. Jim

Jimmy,
If you can't fine an unbreakable one I have them in old blue steel if you are interested...Just email me..
