Haha amplitude is such a pest. The timegrapher is the best machine, but also the worst. Now I am never happyThere are a few reasons for low amplitude and in combination can have a pronounced effect. These can be wear anywhere, dry lube , too much lube, not enough lube ,wrong type of lube, lube in the wrong place, wind blowing in from the wrong direction etc:biggrin:
I know what you mean. Sometimes no matter how much you try to do the perfect service you get the occasional possessed watch and the amplitude disappoints. I usually see what it does in each position and if it is stable under movement do not worry about it. Then again I am easily pleased:93: and its the real world performance that counts for me.
Are you sure they're wound fully?I noticed that most of my seikos have low amplitudes, under 200 but appear to be running fine and keeping good time. Any reason for this ?
