rolli Posted March 1, 2012 Report Share Posted March 1, 2012 for those who have these experience, i have to install a swiss eta 2893-2 gmt movement with original movement-retaining-ring in a pam 029B gmt case which had installed an asia 2836 with gmt function. the asia 2836 has a different measure than the 2893-2 movement, see image. it's 0,25 mm difference. the dial must get an additional 0,25 mm underlay . is it necessary then to use H5 hand extension gears for all hands ???????? or only for the gmt hand ??????? thanks for help rolli Link to comment Share on other sites More sharing options...
FxrAndy Posted March 1, 2012 Report Share Posted March 1, 2012 You may be able to get away with only using the GMT, hour and cannon pin if you have a long tubed seconds hand but if you dont then you will need them all H5 Link to comment Share on other sites More sharing options...
