Ok, I've had my Hamilton Jazzmaster for a week now, and after having handle a few other Swiss Watches, I feel like this Valjoux 7750 in my watch is VERY loud. This is actually a modified 7750, called caliber H-21. Anyway, I've heard of the 7750 wobble and learnt to live with the loud whirring noise of the rotor but....
Below is a link to a video showing the noise I mean. It's not as audible as it is in real life in the video as obviously the iPhone mic cannot pick up the full extent of the noise, but you get the jist. I would definitely not ordinarily tap or flick my watch like this, but have done so for demonstration purpose.
Please turn your volume up.

When I tap the glass on the case, or the side of the case, or when I click my fingers or anything of that nature, clapping etc. I can hear what I think is the rotor scraping or moving in such a way that seems oddly noisy to me. It's almost a clunky noise, possibly not the rotor but the movement moving. I consider it odd as I've said I've handled a few Swiss Autos, and this is not something I noticed about them, but something I notice more in chinese automatics.
Anyway, What do you guys think, is this normal for the 7750, or is there something awry with my movement? I'm concerned as this is not the norm for me in Swiss Auto movements and am not sure if I need to take it to get serviced or fixed in any way.
Thank you for any informative advice!
