Does the A2892 have uni-directional or bi-directional winding?

I just got a V7F IWC Ingenieur in hand, and I noticed the rotor is a bit noisy, sort of like another watch I have that runs the Miyota 9015. I'm just wondering if the winding on this movement is uni-directional, or if I have a damaged watch?

Speaking in broad terms, the eta clones tend to be quieter than the miyotas. You may just need a little lubricant on the rotor bearings. It's easy to do- but be sure you use the proper lubricant- and less is best.

Hi there, sorry for suddenly jumping in, couple of quick questions if you wouldn't mind.

I'm also eyeing for V7F ingenieur and would like to know if the movement is capable of instant date change at midnight? I read from the tech sheet that the original eta2982 has 51 degree lift angle, does the same holds true for the movement used in the v7f ingenieur? thanks

Since it's a direct copy of the ETA 2892, I would expect the same lift angle

What would you use?
9010? D5?

9010 for the rotor bearings mate

thank you sir, most of the qc videos showing timegrapher usually set at 52 degree, suppose it would not make a major difference towards the result then

For our purposes I always leave my lift angle set to 52°. Nothing I'm doing requires that precise of adjustment.... If I need that precise of time keeping I'm better off using my phone anyway...

Forgot to update this. In case anyone comes across this post with the same concern, it was definitely an issue with the movement itself.

I sent this one back for a refund 2 days after getting it, and recently purchased a new one. I got it in yesterday, and the rotor is MUCH better on the new one.
