Help this newbe on repair!

Two problems, both Waltham: different watches:
1)watch runs fine in dial down and stem up, but will stop as soon as it is tilted to dial up.

2)watch runs fine, when winding after about 4th twist it gets VERY hard to wind. I repaced the mainspring (ordered by ser #) and I can not see any obstructions, inside of barrel is smooth.

Any help will be appreciated.

Hi Randy,

Sounds like the first watch has a staff problem. Check the balance staff to see if it's broke or bent. If you are not a watchmaker, I would recommend he does the work. When you mess with the staff you could make it worst than better if you don't know what you are doing. The second watch is a stem problem or oiling problem. If you put a little mainspring oil on the barrel arbors ends and a small amount on the stem gears. Your maispring barrel could be hitting the plates also. A good watchmaker sould be able to cure your problems at a fair price. I hope this helps and have a nice day.

Sincerely, Don

Randy,
If the Waltham with the #2 problem is a Model 1899 or 1908, you might try removing the transmission (or crown) wheel and try lubricating the bearing surfaces between the wheel and the barrel bridge and the central hub. Remember that the screw usually is a left handed thread.

Here are 20 dial up-down problems

1. dirt or thick oil in one or both balance jewels
2. Burred or marred balance pivot(s)
3. End of one balance pivot flat or rough and the other polished and rounded.
4. End of both pivots polished, but not the same shape
5. Pivot bent
6. Hairspring rubbing balance arm or stud.
7. Hairspring not flat or level
8. Overcoil rubbing under balance cock.
9. Over coil rubbing center wheel.
10. Balance pivots fitted too close in jewels
11. One pivot having excessive side shake and the opposite fit well.
12. Escape or pallet pivots bent or damaged
13. Balance end stone pitted or badly out of flat
14. Over coil rubbing outside coil, at point where it curves over spring.
15. Balance arm or screw touching pallet bridge.
16. Balance screw out too far, touching bridge or train wheel.
17. Safey roller rubbing dial plate or jewel setting.
18. Fork rubbing impulse roller.
19. Gurard pin rubbing edge of safety roller.

These are from Kleinlein's book. That should keep you busy for a while. It is not a complete list.

Randy,
I had my fingers in motion before my brain was in gear. The Model 1899 and 1908 Walthams use a RIGHT handed screw to hold the crown wheel.
Most American makes used a left handed thread, but Waltham was an exception, as their hub had a slot in it which engaged a screw head in the barrel bridge to keep the hub from loosening.
My thanks to Jack Kurdzionak for letting me know about the error.
