neils Posted January 31, 2010 Report Share Posted January 31, 2010 Sorry, this has probably been asked a thousand times, but i cant find one of them via the search. This is actually on a Hublot Big King, which uses a 7750 with all the chrono parts stripped off. I had to adjust the spring tension and cam screw to get the running seconds to even work properly, as it just kept stopping because the transfer gear was not engaging onto the seconds wheel. Works fine now but very jumpy and obvious to the eye. Is there away to rectify the jumpy seconds hand, or is it a question of adjusting the cam and spring tension until it runs smoothly. I am newly self taught watchmaker and strip these 7750's on a regular basis so pretty up on the understanding of the works. Can a more accomplished watchmaker point me in the right direction please? King regards Neil Quote Link to comment Share on other sites More sharing options...
