51NGH Posted December 2, 2012 Report Share Posted December 2, 2012 Guys What is the deal with the movement in APs? I am reading conflicting threads and thought everyone would like some clarification. I just got my first AP Chronopassion and the chorno function didn't work on arrive. The TD has been amazing and is sorting it all out for me, but I want to know if I can expect problems with this movement going forward? Would be rather sad to be wearing an AP and see it stop/break when dishing out over $500 for one! Quote Link to comment Share on other sites More sharing options...
umaz662 Posted December 2, 2012 Report Share Posted December 2, 2012 yep reliable Quote Link to comment Share on other sites More sharing options...
Rolexman Posted December 2, 2012 Report Share Posted December 2, 2012 they snap back so violently they sometimes snap the oscalating pinnion and the chronos stop function.. Absolutely none sense. The osicilation pinion can't be engaged when the chrono cam is in reset mode. Therefor resetting does not influence it any way. The movement is reliable except for the extra aded second transfer gears (to transfer the seconds from 9 to 12). There are some tricks to make this modification reliable though. 1 Quote Link to comment Share on other sites More sharing options...

OceanView Posted December 3, 2012 Report Share Posted December 3, 2012 I've heard both good and bad experiences with the modified movement. I just don't want to take a chance on a $500 watch though. Quote Link to comment Share on other sites More sharing options...
watch.aholic Posted December 4, 2012 Report Share Posted December 4, 2012 Hit or miss methinks.....I bought a Safari with the newer modified @12 movement (I think they say it's got an extra jewel or something)....it ran Ok for 3 weeks or so and then started slowing down....so now I've got no choice but send it for servicing....After servicing though, I am hoping it'd be a stellar movement....

txcollector Posted December 4, 2012 Report Share Posted December 4, 2012 There are two type of rep AP ROO movements out there: 1) the older ones where the 12 o'clock running seconds gear rests on bare metal. 2) the new one where they finally put a jewel on the plate Obviously the older models were a problem due to friction so a few modders used to offer a service that was basically putting a graphite powder on the plate to reduce friction. That was a double edge sword since you really don't want powder floating around your engine. http://www.rwgforum.net/topic/113958-improving-the-reliability-of-ap-seconds-at-12-movement/ The new version seems to be very reliable but it's still the good old A7750 under the covers so if you are experiencing issues (slowing down, hands not resetting, etc.) get it serviced.

Rolexman Posted December 4, 2012 Report Share Posted December 4, 2012 Never ment to say when resetting but when starting the chrono is where the problem is. Sorry. Also not the case. The tilting pinion engagement is not an issue on any A7750 or ETA for that matter. TX's story sums it up pretty well. Quote Link to comment Share on other sites More sharing options...
Watchmeister Posted December 4, 2012 Report Share Posted December 4, 2012 TX's story sums it up pretty well. +1. You are better off with the newer movement which actually has the jewel. As to how well it runs it will be the same potluck as any other Asian 7750. I tend to not service them until they need it but that is personal preference.

hiker01 Posted December 4, 2012 Report Share Posted December 4, 2012 I have no experienced with the jeweled version, but the 4 older models I have all sucked. I had them serviced and graphite, but it did not last for long. I'm thinking of freezing the sec@12, but not yet! Quote Link to comment Share on other sites More sharing options...

Ketjap Manis Posted December 13, 2012 Report Share Posted December 13, 2012 Is the Chronopassion a jewel model? I would like to know that too! I'm thinking of getting the V5. Quote Link to comment Share on other sites More sharing options...
FxrAndy Posted December 13, 2012 Report Share Posted December 13, 2012 To be brutally honest I stay well clear of any movement modded away from its original design. Add complications and you add chances of it going wrong Same problems with the IWC Portuguese and the Rolex Daytona an they all involve a movement where the runnin seconds have been moved from its intended location to another area Quote Link to comment Share on other sites More sharing options...

The tri-compax sec@6 on the Daytona is a much harder modifications for the 7750 than sec@12. I have no idea why they can't just fix the Portuguese though. With the new AP movements I haven't seen any issues at all. Quote Link to comment Share on other sites More sharing options...
peterpl Posted December 14, 2012 Report Share Posted December 14, 2012 AP sec@12 is more reliable than sec@6. I've got 4 APs. None of them have stopped working and I've had them for over 1 year now. Quote Link to comment Share on other sites More sharing options...
horologik Posted December 29, 2012 Report Share Posted December 29, 2012 it s a hit and miss. i have had 6 of them, and as of now the longest running ones were the ones that have been serviced. Quote Link to comment Share on other sites More sharing options...

IWC does a much better job of it and jewels everything, of course, but the IWC 79350 is essentially just a regular 7750 with a transfer plate.

JKDDUDE Posted January 5, 2013 Report Share Posted January 5, 2013 I've got 4 ROO's, and the only thing I've done is never keep them on a winder. I wear them for a day or two and put them away for a month or so -- they seem to do best when worn for limited duration. They definitely need a little more planning than the average rep, but then again, they are worth it:) Quote Link to comment Share on other sites More sharing options...

You'd be crazy to put a sec @ 12 or sec @ 6 7750 on a winder, just puts constant stress and wear on its most vulnerable points. Quote Link to comment Share on other sites More sharing options...
RT210 Posted January 7, 2013 Report Share Posted January 7, 2013 I got hit with a bad model - AP RB3 stopped working the day it arrived. Its now shipped back to the dealer and hopefully will get back in a few weeks - fixed for good Quote Link to comment Share on other sites More sharing options...
JKDDUDE Posted January 18, 2013 Report Share Posted January 18, 2013 RT, that sucks! The next one you get will probably be a keeper! Quote Link to comment Share on other sites More sharing options...
Theknowledge Posted January 18, 2013 Report Share Posted January 18, 2013 It is very practical that there is a topic about the movements as I seem to have a problem with one of mine. Can anyone tell me what is wrong with it? It works by shaking or winding but only lasts for 4-5 minutes then stops. I imagine this has to do with the power reserve, but I already sent a message to UWE to see if he can fix it, but whilst waiting to hear back from him I would appreciate some advice, is it an easy fix, or should I leave it for a pro. I would also like to mention that even after winding it 35 times it still only works for 4-5 minutes. Thanks in advance Quote Link to comment Share on other sites More sharing options...
JKDDUDE Posted January 19, 2013 Report Share Posted January 19, 2013 TK -- The problem lies in the added gear to move the seconds from 9 to 12. The movement needs a service and it will run fine. No fun, but just the reality of these great watches:) Quote Link to comment Share on other sites More sharing options...

Not sure who told you to do it. I'm not sure what model you have so it's very hard to know. It could be a number of things from dirt, to lack of oils to a busted mainspring. Whatever the issue is nothing with a 7750 is an easy fix. Send to Uwe. Quote Link to comment Share on other sites More sharing options...
