I just serviced a 1899 Waltham, washed all the parts, oiled, replaced the mainspring, everything went smoothly...only problem is its hard to wind. I used a #2227 0.019 mm strength. I rechecked everything...nothing seems out of line. This the only 1899 I have...maybe they just wind hard? Only other thing I can come up with is a used a spring that was too strong. I see that the spring range from 0.016 to 0.02. Why would they make them at a strength that makes them uncomfortable to wind? Maybe I am missing something. Any input would be greatly appreciated.
