Pugwash Posted May 12, 2006 Report Share Posted May 12, 2006 I asked elsewhere about how to calibrate an Asian 7750 (28800vph, B-model, new one, whatever) and was told to move the bits above the wheel closer together or further apart. I tried this, remembering that I thought one of them wasn't supposed to be moved, but enough people said it should work that it was worth a go. Having tried it, I found that the watch would then stop, as if it just didn't have the energy to swing the wheel round. What am I doing wrong? What am I supposed to be doing here? Is the bit with the two gold pins supposed to be moved or is it the piece above it? My IWC GST Chrono was about 5 minutes a day fast, now it's correct twice a day. Here's some eye-candy to make you happy. Link to comment Share on other sites More sharing options...
JJFlash Posted May 12, 2006 Report Share Posted May 12, 2006 Top adjusts the rate (speed). Bottom ("two gold pins") adjusts the beat. You are now in need of help to correct the problem. ZZ or RBJ. Link to comment Share on other sites More sharing options...
Pugwash Posted May 12, 2006 Author Report Share Posted May 12, 2006 Bottom ("two gold pins") adjusts the beat. You are now in need of help to correct the problem. Or, I can refer to the "Continuity" photos I took of the movement before I started the work. Like a photographic undo button, unless of course this permanently breaks the movement. Thanks, JJFlash.

sssurfer Posted May 13, 2006 Report Share Posted May 13, 2006 Pug, you have been quite successful. If your watch was 5 minutes a day fast, it was correct every 144 days. Being now correct twice a day, you got a 288% improvement. Link to comment Share on other sites More sharing options...

Rolexman Posted May 13, 2006 Report Share Posted May 13, 2006 (edited) Top adjusts the rate (speed). Bottom ("two gold pins") adjusts the beat. I seriously believe this is the other way around!! The hairspring is attached to the lever with the two gold pins so this is the lever for regulating the speed.....

Well, whatever the case, Last night I put everything back the way it was in the first photo and it's running better than before. Obviously, I need to wait a day or two to be certain it doesn't randomly stop, and I'll book it in for a full service, but at least it seems to run ok.

Rolexman Posted May 13, 2006 Report Share Posted May 13, 2006 (edited) For more The Zigmeister info on this topic. I was right about the levers by the way but the hairspring isn't attachd to the lever with the gold pins..... it passes through it.
