Hello there. I've just gotten my new Timegrapher and started to check our watches. I tested this vintage Tissot (20mm long) and the Rate reading was +350 s/d and Beat Error 0.2 ms after I have moved the lever all the way to the left (slowing it down) it reads now +130 s/d but unfortunately the Beat Error went up to 9.0 ms. THis watch haven't used for about 10 years and looking at it, it seems to be very clean, so I guess it might need to be oiled but other than that, what else I need to do? Shall I move the other leverI've marked in the photo (as I understand it regulates the beat rates and I see many warns not to move it)? Thank you for your help!
