Yea i know that test for auto's, but the thing is because Patek's rotor is a mini rotor, i was afraid that it might not work well, like maybe i cant hear the whirling sound of it.
And unfortunately my mom's Ellipse doesnt have a second hand, its the 2 handed type, so i either have to listen to it tick, or wait a few minutes to see the hands actually move position.
Thanks for the advice on the oil too!
Cheers
Stephen
