Hi, may a professional take a look:



amplitude seems OK ?
watch is an AIRAIN chrono -> valjoux 222 (?)




thanks for any input

You'll want to check that the lift angle is set correctly (apparently 48 degrees) if you want to interpret the amplitude. It might also be helpful to measure the watch in a few positions.

Lift angle should be 48 degrees for that movement, so if that it what you have (I cannot make out what is in the cartouche very well) then if you have the machine set for 52 degrees, the amplitude is lower than what the machine is telling you.

Aside from that, we have no information on what the state of wind is, or what position the movement is in when the reading shown was taken.

If you want to get more input, a full set of measurements over 6 positions at full wind (30 to 90 minutes after fulling winding the watch) is a good start, with the machine set to the correct lift angle.

Thanks Dan 馃憤 , the watch is not im my hands.....
You can ask for what I have outlined above. But other than that, what claims are being made? Has the watch been serviced? If so is there evidence of that? Who did the service?

Without actual proof of a recent service by someone who is known to do good work, then I would count on having a service done as part of what you should pay, if in fact you are considering a purchase. More context when asking these questions would be very helpful in getting useful answers...

I am not sure, if the seller ist watch-maker. I will ask the "seller" the mentioned details. Lets wait ;-)
thx@all

I'm not seeing anything of concern in the readings. If the owner left the lift angle set to the default value of 52藲 and the actual LA is 48藲, then the true amplitude would still be about 275 IIRC, which isn't too bad.
