watcher Posted February 23, 2008 Report Share Posted February 23, 2008 I'm wanting to swap out an asia7750 28800 movement for a swiss eta in my 'slevin' AQTimer and just need to know which hands need correcting. The Zigmeister once posted all this info but for some unkown reason he has deleted the info on the post(thanks The Zigmeister!!!) Thanks in advance Paul Link to comment Share on other sites More sharing options...
sssurfer Posted February 23, 2008 Report Share Posted February 23, 2008 The Zigmeister's info: Genuine ETA 7750 all variants (all): Hour 2.00mm Minute 1.20mm Center Seconds 0.25mm Subdials 0.17mm Old Asian 7750 version all variants(21,600 BPH): Hour 2.00mm Minute 1.20mm Center Seconds 0.25mm Subdials 0.17mm New Asian 7750 (28,800 BPH) Normal ones - NOT the Daytona model (don't have one to measure): Hour 2.00mm Minute 1.20mm Center Seconds 0.20mm Subdial 0.20mm Also note on the New 7750, the center seconds post, is below the top of the minute hand tube. On all other versions of the 7750, the center seconds post is about 1mm above the minute hand tube, not below it. Therefore the center seconds hand on the new 7750's, has an extra long tube on it, to make up this height difference. So not only is the hand smaller in diameter, it's longer as well...

takashi Posted February 24, 2008 Report Share Posted February 24, 2008 The Zigmeister's info:...... Also note on the New 7750, the center seconds post, is below the top of the minute hand tube. This is no longer true for all Asian 7750 hi beat. The length of the tube is about the same. Link to comment Share on other sites More sharing options...
