So a little update, no joy! in fact the hour hand now skips whilst winding! As annoying as that is i didnt have to wait hours to see if the bloody hour hand stopped. Weird thing is it was always roughly around 3 oclock and around 7 oclock it stopped. Last chance saloon before i throw the bloody thing away is go through every tooth of ever wheel related to the problem, and check side to side play in the intermediate date wheel. Im rapidly losing hope of ever getting it to work! I checked the plate to check its parallel, its within 0.02 mm, total height is 0.19mm +/-0.01. Seems like it cant be vertical play but never say never i guess!
Yep, noticed the hairspring, nice touch. REMOVE the date corrector and the 2 intermediate wheels and see if that stops the hour hand moving while winding. If those are still in place, you have a link to the hour wheel from the setting wheel in crown position 2, and you might have a sloppy keyless halfway toward position 2.
