Rotor Squeak normal on the P15?
I haven't worn my P15 in 3-4 months, after putting it on today and arriving at school, I hear can hear a distinct squeak noise (like a mouse) eminating from the timepiece (ive narrowed it down to what appears to be the rotor) as I move my arm occasionally (along with the usual rotor winding noise), is this a normal noise? have any other members in our community experienced this ? What is my next step, sending her off? Any advice is appreciated as this is the first time I’ve encountered this on a timepiece. Thank you all for your suggestions.
All fine
The P15 sounds like as if there is quite a lot going on , when I shake it, while writing this.
There is nothing wrong with that: Omegas, even Pateks sound sometimes like that too 
!
! It sounds different than what it used to, ill try and record it tonight but its a definite squeek, the usual sound of the rotor is similar
To my Omega, Vacheron, Seiko etc, but the new sound ive observed is worrying me a lot. In the middle of the normal sound, (like balls rolling the easiest way I can describe it) there is a sound similar to a mouse squeak that appears occasionaly, have you been able to hear this sound on yours Count De Monet? Thank you for checking and your advice
tried again
I do not hear any high frequency noise from the movement. It is just the usual rattle. I only hear any noise if I hold the watch close to my ear. Away from my ear I do not hear anything
You almost want to worry in the other direction is it too quiet. Lol. [nt]
No message body
Ill try to record the noise tonight am so hopeful this is normal for the rotor as it gave me a shock today when I heard it. [nt]
No message body
My experience is that kind of noise is often the rotor barely touching something inside
It can be a loose pivot due to wear (very unlikely with a P15 as it's so new) and more often caused by a loose screw in the movement winding system, or even the hold-down screws of the movement.
Compare your watch to these photos of my watch using a loupe and good light. If you don't see anyuthing amiss when you carefully inspect the movement through the caseback, and the noise continues, you should probably have it checked out. A competent local watchmaker could inspect it for you - the El Primero movement is well known.
Here are some photos of my friend Moki's Tudor, whose movement screw came out and driftet over near the stem (thankfully not into the balance).
Thank you so much for the pics and I was assuming it could be the case but was hoping it is not too serious...
Will video it tonight after arriving home and see
Thank you so so much Magnus I’ll try and video it tonight (the sound at least) can I email you the video ? [nt]
Just recorded the noise and sent it via email, thank you so much for checking in on this
Rogi, the Zenith team thinks that this is due to improper oiling of the rotor's ball bearings...
the question is now: does it wind properly when you wear it?
Cheers,
Magnus
Thank you Magnus for checking with Zenith, when I wear my P15, I didn't notice any deviation in winding (only the noise itself) or power reserve, as I hadn't worn it for a long time,
the first thing I did yesterday was to wind it via crown (to around 15-25 rotations). Then when I arrived in school that was the first time I noticed the noise (it is progressively getting more frequent). After arriving home, I set the timepiece aside and so far it has been keeping time. I'll let it wind down completely and then redo with just wearing it on my wrist with a slight winding of the crown.
What would be the next step to take?
Thank you

From the initial wearing, (the full wind and wearing all day), my P15 held a power reserve of about 33 hours, I took some time this weekend and observed that from a small wind (ie 5-10 turns) and
me having it on my wrist for a lazy Saturday (around 10 hours of wear, with the mouse noise increasing in frequency) it kept 7-8 hours of power reserve (a little past overnight) stopping in the morning, when I picked it up in hand again to check the power reserve it started working and lasted another hour till full stop. (I checked back every half hour). Timekeeping has reduced as well, previously it kept a 1-2 seconds loss/gain on average and in the initial day it had a loss of 5 seconds (when I used my app to measure it) which is still within COSC specs but the power reserve loss concerns me a lot. Thank you for your advice and help Magnus.
