Ronin Posted January 7, 2012 Report Share Posted January 7, 2012 First, if you have not read this: http://www.rwg.cc/to...nds-6-movement/ -- Read it. I pulled this off the back burner, hell bent on: 1.) Freezing a Center Seconds, 3 & 9 Subdials, for what could be a reliable Center Seconds Daytona. (But non-working chrono, so appearance only) What I found, and it can be done.... CAUTION - Working on this movement requires a similar skill set to working on a 7750. The Auto-Winding assembly was never really meant to be disassembled on this otherwise 'disposable' movement. Pics to explain it all: I will keep you updated.... 2 Quote Link to comment Share on other sites More sharing options...

Paneraibob Posted January 7, 2012 Report Share Posted January 7, 2012 Why would you do all this work if you could buy a Daytona with frozen hand and running second @ 6 PWC did sell them, now that he is dead R.I.P. Robert maye another dealer can source them but i guess it is easier to source such a watch then modifying these movements http://www.repgeek.com/showthread.php?t=158052 Quote Link to comment Share on other sites More sharing options...

jimmy Posted January 7, 2012 Report Share Posted January 7, 2012 I have Roberts Daytona and it's running flawlessly, each day though the hand at 3 & 9 mov, I guess that was for the day date feature on the 21j, I just reset it each day back to zero, this I hope will be the future, movt anyway!!

Star69 Posted January 7, 2012 Report Share Posted January 7, 2012 i just saw yesterday an Daytona with running Sec at 6 - and a lot of APs at Domis workplace - i can say that he found now an working cure for this movements - has nothing to do with tha fix that Francesco posted some years ago. the Daytone had a power reserve form nearly 3 days - super smooth sec hand an healty beat rate. cheers, Frank Quote Link to comment Share on other sites More sharing options...
robertk Posted January 7, 2012 Report Share Posted January 7, 2012 I've had my Daytona seconds at 6 for more than 3 years. No fix. It still works flawlessly. Talk about luck! Quote Link to comment Share on other sites More sharing options...
automatico Posted January 7, 2012 Report Share Posted January 7, 2012 Ronin... Thanks for the pictures! They make it much easier to understand. "I have Roberts Daytona and it's running flawlessly, each day though the hand at 3 & 9 move, I guess that was for the day date feature on the 21j, I just reset it each day back to zero..." The subdial hands at 3 and 9 are easy to freeze while the dial is off. The modification to your watch may have been done by freezing only the center sweep hand from the back without removing the H, M, subdial hands, and dial. If you do it this way, all you have to do is what is shown in Ronin's pictures. The watch I modified is still running fine and probably has around 2000 hours on it by now. I even loaned it out a few times...maybe I could start Rent-a-Watch and get rich! Rats. First Watch Leasing dotcom beat me to it. "I've had my Daytona seconds at 6 for more than 3 years. No fix. It still works flawlessly. Talk about luck!" A friend wore a sec at 6 A7750 most of the time for about 3 years with no trouble before he lost the crown and stem out of it. He hardly ever ran the chrono timer though. I guess it's the luck of the draw. Quote Link to comment Share on other sites More sharing options...
jmb Posted January 7, 2012 Report Share Posted January 7, 2012 Why would you do all this work if you could buy a Daytona with frozen hand and running second @ 6 Well, Bob, why do people climb mountains?

Plastiker Posted March 6, 2015 Report Share Posted March 6, 2015 FINALLY!!! I came across this tutorial!!! Thank you automatico and Ronin for the input!!!! I am looking for days on the net for this Mod.... The chinese movement is called DG3836P and can be found easily on the net. Cost around 30$... So no much waste if it does not work the first time:-) Quote Link to comment Share on other sites More sharing options...
