Good morning, I have an Omega from 1930 (caliber 40.6L T1). After many years standing, a month ago I took it cleaning and lubrication review. Back home, horizontally forward about 15 seconds a day and upright in about three minutes, per day. In the Timegrapher (for iPad) it gives greater amplitude in vertical than in horizontal. Is this normal in a clock of the early 30s? How to adjust the clock better? Thank you. I attach images of the result of the chronocomparator and of the movement, as it behaves with those variations of march according to the position.
I would find another watchmaker - the service was clearly not done correctly. The readings in the vertical position are so erratic I'm not sure I would trust them...
