dez82 Posted March 18, 2009 Report Share Posted March 18, 2009 Background story I ordered an AP ROO black dial from a dealer that was listed in this forum a few months ago but is no longer (I don't know why). The watch I wanted to get was an AP ROO with secs at 9 but with correct subdial positions (like the MBW). I e-mailed him a link to another watchdealer that had a watch like that because I couldn't get into his webshop to see if he had that watch. And I got a good price because he didn't have this watch in his shop. I paid and he sent the watch. When I got the watch it didn't work. And it was very noisy when I turned it around. The thing is that the watch really looked like an AP ROO secs at 12 but I just thought they had made a watch with secs at 9 with exactly the same dial as the secs at 12. I sent the watch back for repair and today I got it back. When I took it out of the box I could see that it was working but to my surprise it was a secs at 12. Really strange because it was the same watch i got the first time that was sent back but I had ordered and paid for a secs at 9 (paid 295 usd). The thing is that the watch is still noisy and I wonder what it could be? I don't wanna send it back to China one more time. Is it something that I maybe can fix by myself? Or should i send it to some watchsmith here in Europe? (read about a german guy). What do you guys think, can you give me some advices.

rogerthat Posted March 18, 2009 Report Share Posted March 18, 2009 Noisy how, like the rotor spinning? Maybe you could just tighten the rotor. Quote Link to comment Share on other sites More sharing options...
dez82 Posted March 18, 2009 Author Report Share Posted March 18, 2009 (edited) I don't know exactly how to describe it. Maybe it is the rotor. It is some kind of metallic sound, scratching. The firts time I heard it I thought it was a screw loose inside the watch. How do you tighten the rotor? Maybe some good pics somewhere?

rogerthat Posted March 18, 2009 Report Share Posted March 18, 2009 The rotor should spin freely on this movement, so it will make a little noise but with the big metal case of an AP ROO it should not be very audible. The caseback can easily be opened with a screwdriver, see the 8 screwheads on the back. Unscrew them the case back comes off and you will be staring at the rotor. When you look at the rotor and movement you may be able to see what is making the noise. Just be careful not to get dust into the movement while the caseback is open and you will be fine. No special tools or skills, just 1 screwdriver. Best of luck. Quote Link to comment Share on other sites More sharing options...
dez82 Posted March 19, 2009 Author Report Share Posted March 19, 2009 Ok, thanks for your input. I will try tonight to open it up and have a look inside. I will have to pull out the crown first before I open it up, right? Quote Link to comment Share on other sites More sharing options...
Samurai Posted March 19, 2009 Report Share Posted March 19, 2009 If you ended up getting a sec @ 12 for $295.....you got yourself a steal mate.....don't send it back... Quote Link to comment Share on other sites More sharing options...
dez82 Posted March 19, 2009 Author Report Share Posted March 19, 2009 (edited) Yea I know. I just have to fix this problem. Edited March 19, 2009 by dez82 Quote Link to comment Share on other sites More sharing options...
kronos twin Posted March 19, 2009 Report Share Posted March 19, 2009 maybe it's not simply a matter of tightening the rotor, but also lubricating the ball bearings on the rotor wheel itself. It sounds like those bearings are not lubed enough, causing that sound. You might consider either lubricating them yourself or having someone do that.

dez82 Posted March 19, 2009 Author Report Share Posted March 19, 2009 I don't think I'm able to do any lubrication as I have never even opened up a watch before. I will open it up tonight and have a look if I don't can fix the problem then I have no other possibility then to send it away to someone.

dez82 Posted March 22, 2009 Author Report Share Posted March 22, 2009 I opened the watch but I couldn't find any obvious faults. I think the rotor was tightened enough because it couldn't be tightened more than it was but I didn't put that much power on it to avoid breaking anything. The rotor spinned very smooth and it didn't make that much noise when it was spinning around. The noise came when the rotor was moving back and forth in the same place and that was in the lower part of the movement. I couldn't see if the rotor was touching anything but it didn't look like it did that. Maybe it's just a case of lubcrication of the ball bearings on the rotor wheel as kronos twin said. Because it sounds like it is the rotor that makes the sound when it moves in a specific place. When the power reserv went out I couldn't make the watch start just by shaking it and I had to wind it 5-10 times and then it started to run again. Is that common with this modified 7750 movement? I have now ben using the watch for three days and it works perfect. It is just sometimes it makes these noises and it is when I shake my hand or maybe put my hand up side down and it is probably because the rotor moves back and forth in this specific place.
