moggy Posted October 27, 2009 Report Share Posted October 27, 2009 Hi guys, when I set the time on my BS the minute hand doesn't move for a minute after setting. i.e. I set the minute hand on 12, wait for the time source minute to also reach 12 then push the crown in to restart the watch. When the time source is showing 1 min past mine is still sitting at 12. When the source shows 2 min past mine now shows 1 min past. If I set the time a minute fast then after 1 min everything is equal. Any info as too why? I might add that I know of one other BS that does the same thing. Bob.

wheaton26 Posted October 27, 2009 Report Share Posted October 27, 2009 my blacksteel is the same. not sure why but all watches set differently. even my gen panerai isn't exact (15 seconds or so off). nothing to worry about and very normal.

FxrAndy Posted October 27, 2009 Report Share Posted October 27, 2009 I would put this down to the play in the gearing between the hour and min wheels. it would be reasonable to assume that gearing made with older tooling would have more (or less depending on if they are stamped or cut) play than new tooling. I have just had a play with 4 unitas/seagull 6498 3 2824s and 2 A7750 and the 7750 has the most play in this area, and the seagull the least, maybe Ziggy or Francisco can explain if my theroy is correct and if some one can have a play with a swiss 7750 and see if that also has play.

ChipSlap Posted October 27, 2009 Report Share Posted October 27, 2009 I have about 1 minute of play in my A7750 IWC 3717. But, even my gen Hamilton with Swiss 7750 has about 20 seconds of play. Quote Link to comment Share on other sites More sharing options...
andreww Posted October 28, 2009 Report Share Posted October 28, 2009 All my 7750s do that. Got in to the habit of setting the 1 minute ahead a long time ago. Quote Link to comment Share on other sites More sharing options...
unit17 Posted November 21, 2009 Report Share Posted November 21, 2009 My blacksteel is exactly the same, set it 1 minute fast to take up the slack in the movement. Quote Link to comment Share on other sites More sharing options...
sander Posted September 29, 2010 Report Share Posted September 29, 2010 Yes it has to do with play between the gears. Also some gens have these kind of problems. For instance the minute hand of my gen Franck Muller, jumps forward a little when I push the crown back in. Regarding the play you can try the following: When you set the time, just set the minute hand a little too far and then turn it back to the right time. so if it's 15 past, set it at 18 past and turn it back to 15 past. The problem should be gone. Quote Link to comment Share on other sites More sharing options...
cougaree Posted September 30, 2010 Report Share Posted September 30, 2010 Yep. That's what I normally do. Quote Link to comment Share on other sites More sharing options...
