Rolexman Posted September 29, 2012 Report Share Posted September 29, 2012 Although I have a lot of experience in servicing movements. I'm relatively new to the Seagull ST19. I did service a lot of 7734s and other manual wind chrono's but today I did my first ST19. The thing I noticed was that there is no way to adjust the hammer reset. After resetting, the chrono second wheel has a tiny amount of play. Where the 7750 has a self levelling hammer and the old 7734s have a adjustment screw the ST19 has nothing. So it seems. Am I missing something? Mark Quote Link to comment Share on other sites More sharing options...
