hackR Posted April 2, 2012 Report Share Posted April 2, 2012 On the watch I'm wearing today (a 6-9-12 a7750 ss Chrono Avenger franken), i have to set the watch exactly one minute ahead of my computer time to sync it...the watch's power reserve has juice - so essentially i'm hacking it (pun intended) at 00 and then setting the time, pushing the crown in when the computer i'm syncing with hits the 00 mark...make sense?...In other words, if i'm trying to sync the watch at 3:17pm, i stop the watch at 00 seconds and set the watch to 3:18...then the watch is aligned with my computer...for some reason, this has to be done...i'm pretty sure i've had other a7750's where i needed to do this, as well...but many of my a7750's do not function this way...what's also odd on this one is: it's not serviced, has this one second "quirk", but it keeps almost COSC time... weird...anyone else have this "problem"?...or know why this is the case?... thanks...R Link to comment Share on other sites More sharing options...
Justasgood Posted April 3, 2012 Report Share Posted April 3, 2012 The valjoux movement needs to be set with the hands moving clockwise and the slack in the gears will track. If you set it like an eta(counter-clockwise) it will take that minute for the slack to be taken up. Some valjoux's will need a 30 sec. advance when setting the CCW. Bugs the [censored] out of me.

Ronin Posted April 3, 2012 Report Share Posted April 3, 2012 From the GEN 7750 Manual that comes with all SINN watches. The way I do it on all my 7750's Gen's or Reps is to go PAST the time and "back it up" to the correct time, taking the slack out of the gears. Viola! (To be fair, this only works about 80% of the time, because any rotation when pushing in the crown will mess with the slack). HTH Link to comment Share on other sites More sharing options...

Watchmeister Posted April 3, 2012 Report Share Posted April 3, 2012 +1. But not all my 7750's require it. Link to comment Share on other sites More sharing options...
