Hi all. I just received a 116900 BP which has a 2836-2 movement inside. The rotor seems quite noisy so I opened it up to see if anything obvious was missing or broken, everything seems fine. One thing I noticed though is that the rotor plate and rest of the movement is silver, whereas on all the TD photos, it's all gold? Can anybody shed any light? Is the photo of mine definitely a 2836-2 movement? Cheers all
