[1908]

Hello,

Could someone please tell me if this the correct mainspring for a Waltham model 1883 7 jewel movement (1889)?

WALTHAM P/W MAIN SPRING #2205 T x .22mm 18s Model 1883 STEEL

Many thanks for any help

Yes, the #2205 is the correct spring for the model '83. Note, however, that steel springs have not been made in decades and may be set and/or subject to rust.

White alloy springs are available on line. Ebay, Dave's , etc. Worth the investment for anything you want to carry. Make sure your safety pinion works if you use blue steel....

If you see that there are a few different strengths, or thicknesses, offered, yours probably needs the thicker/stronger one. Generally the lower jeweled grades take the stronger and get thinner as the watch gains jewels. Good luck.

Glad I asked here first before making a mistake. I never realised there are springs made in white alloy. I'll look for the thicker and stronger spring. Many thanks all.
