EMM Posted June 24, 2011 Report Share Posted June 24, 2011 Hey, question for the experts. I've seen a lot of vintage Daytonas lately posted with a description that includes "6:00 subdial frozen" as a mod. I get why this is a good idea on the modern A7750 sec@6 Daytona, but why do you do it on the vintage sec@9 models? The 6:00 dial is the hour counter - doesn't seem like it would come up much. Thanks.

Mickey Padge Posted June 24, 2011 Report Share Posted June 24, 2011 Usually because the watch isn't using the tri compax A7750, but the venus clone movement, or DW's "mystery movement". Those two movements are not tri compax, but bi compax, and that means the 6 subdial doesn't function, it's just for show Quote Link to comment Share on other sites More sharing options...
z80 Posted June 24, 2011 Report Share Posted June 24, 2011 I thought it was because the subdial at 6 runs all the time on the manual rep movements and on the gen it should only move when the chrono is running. Better for it not to run at all than run all the time. Quote Link to comment Share on other sites More sharing options...
FxrAndy Posted June 24, 2011 Report Share Posted June 24, 2011 It depends on which st19 movement they are useing, you get differen varients (the ST 19 is the movement in these new daytonas and the old moon watch reps and loads of others, the good news it is a fantastic movement) 12 hour constant running @6 24 hour constant running @6 No counter at 6 power reserve @6 but there is no seagul ST19 with a chrono 12 hour counter @6, which is shame as it would be a bonus!!

Mickey Padge Posted June 24, 2011 Report Share Posted June 24, 2011 Ah yeah, I remember seeing the 6 subdial follow the motion of the hour hand before, much better to freeze it Quote Link to comment Share on other sites More sharing options...
Rolexaddict Posted June 24, 2011 Report Share Posted June 24, 2011 What you need to know : The gen Daytona powered with the v727 or v72 tri compax have a shorter spacing between the 9 and 6 subdials hand axis. Using these Chinese crapy mechanical movements with a frozen hand at 6 gives the apparence of a real Daytona Cosmograph. The difference is only 0,6mm with the v7750 series movements between axis, and the advantage is to provide a full tri-compax fonctions. Only anals can notice the difference. For myself, I prefer a full tri-compax fonctions than a handicaped watch, who, even with the correct sub-dial spacing; is still a fake. Be realist. Finally, put just 40.000 usd in, and you will have a gen Cosmograph Quote Link to comment Share on other sites More sharing options...

For myself, I prefer a full tri-compax fonctions than a handicaped watch, who, even with the correct sub-dial spacing; is still a fake. Be realist. This is true. At a glance and at a distance, it is very difficult to detect the 0.5mm difference in subdial spacing. Try this test: You have five seconds to say which one is the V72. Go!
