bklm1234 Posted October 20, 2006 Report Share Posted October 20, 2006 (edited) in terms of durability. I understand those with second at 6 should be avoided (is it 11 gears to get the second at 6?). Is the 6, 9, 12 configuration (like IWC GST) better than the 3, 6, 9 (like Panerai Daylight) configuration? Thanks.

Rikske Posted October 20, 2006 Report Share Posted October 20, 2006 The 6-9-12 (running seconds at 9) is best because this is the original 7750 layout (no mods required). The 3-6-9 with running seconds at 9 requires 3 additional gears to move the minutes subdial to the 3 position and results in the datewheel sitting too deep. The 3-6-9 with running seconds at 6 requires 11 additional gears to move the minutes subdial to the 3 and the running seconds subdial to the 6 position. Here also the datewheel sits too low and power and durability problems are to be expected. For details please see The Zigmeister' s reviews.

andreww Posted October 20, 2006 Report Share Posted October 20, 2006 Basically stay away from any 7750 with seconds at six, or with GMT. Quote Link to comment Share on other sites More sharing options...
