Francisco Posted July 28, 2009 Report Share Posted July 28, 2009 INTRODUCTION. The Asian 7750 movement, a clone of the ETA 7750, has no precision accuracy regulator. This regulator helps to obtain a better adjustment easily. However, this is not so important. With the A7750, without this precision regulator, it is possible to obtain good adjustment. The problem arises with watches where the case back is transparent. In these cases, it is very easy to detect that the watch is a replica. For example, the Hublot Bing Bang. In the webpage of Hublot there is a small tuto for distinguishing a replica, and the regulator is one of the main points to look for. A picture from this website: One of the solutions is to employ an Asian 7750 working at 21600 bph. However, this movement seems to be more problematic that the version working at 28800, with has no regulator. On the other hand, there is a new version of Asian 7750 at 28800 with has a regulator. However, this new movement is still not present in the Hublot replicas and probably is going to be more expensive. In this small tuto we show how to add a regulator to an Asian 77500 at 28800, using genuine parts of the ETA 7750. MATERIALS. Quote Link to comment Share on other sites More sharing options...

chrgod Posted July 28, 2009 Report Share Posted July 28, 2009 Your tutorials are really excellent, especially with the photos! Thanks a lot, I might well try this for my Tag Heuer Carrera. With a display caseback the missing regulator is obvious. Quote Link to comment Share on other sites More sharing options...
