greg Posted November 21, 2006 Report Share Posted November 21, 2006 Hi guys. I bought one of the breitling navitimers with asia 28.8k mvmnts (like the one by-tor won) Now here's the plan 1.order a swiss valj 7750 from ebay with same sub dial placement 2.when, not if the asian fails, swap in the swiss is this feasable, what are the issues? I know the swiss 7750 comes on 12-9-6 and also 3-6-9 placement. So if the sub dial matches then i assume I am good. I may aslo do this with the pam 212 or 253 if i can decide which one to get any thoughts on this one also. This way I give the 28.8k asians a chance and if they fail i am not left with a nice paper weight. And by then i would have completed my watch class.java script:emoticon('', 'smid_12') Quote Link to comment Share on other sites More sharing options...
Rolexman Posted November 21, 2006 Report Share Posted November 21, 2006 (edited) uuuuuhhhhh..... WRONG.... hands are a different diameter. You need to order genuine hands if you want to fit the ETA. The old Asian was an easy swap... the new Asian is not. Look in the Expert Area... The Zigmeister has some info on the hand sizes.

slickdick Posted November 21, 2006 Report Share Posted November 21, 2006 (edited) and The Zigmeister has another threat about converting swiss 7750 to swiss + asian tri-compax module sorta speak, to make it 3,6,9. in his case its a pam of some kind. this will not fix the datewheel depth though. For that you will need a 7753 Edited November 21, 2006 by slickdick Quote Link to comment Share on other sites More sharing options...
Finepics Posted November 21, 2006 Report Share Posted November 21, 2006 But a 7753 is no good in a 7750 watch as the date window will be in the wrong place. The 7753 datewheel is a bigger diameter. Quote Link to comment Share on other sites More sharing options...
bkdc Posted November 21, 2006 Report Share Posted November 21, 2006 Again, if anyone knows where to get genuine Breitling hands, please share the info. I dislike using epoxy on my subdial posts. Quote Link to comment Share on other sites More sharing options...

The Zigmeister has some info on the hand sizes. thanks for the input I don't mind buying new hands especially genuine. How much do they usually run. And once I get the hands is it as simple as swapping the movements thanks again Quote Link to comment Share on other sites More sharing options...
andreww Posted November 21, 2006 Report Share Posted November 21, 2006 I would suggest that you pick up an older version Navitimer. They come up for sale from time to time and go for pretty cheap. This will allow you to do an easy transplant of the swiss movement. (This is for the 6-9-12 version) There is no 3-6-9 swiss 7750. They use a 7753, which is a completely different beast. To transplant a 7753, you will need an older 21k rep, a swiss 7753 movement, a genuine dial, and a lot of patience. The gen dial is slightly bigger than the rep, and will have to be ground down to fit the case. Then its a straight swap. Hope this helps!

Thanks andrew I think the best thing then is to get the a few spare asian movements when I buy my watch. has anyone done this ? what dealers can provide you with a few spare 28.8k 7750's and how much should they be roughly? this may be a better option.

RWG Technical Posted November 21, 2006 Report Share Posted November 21, 2006 For all the time and money, why don't you just service the movement you have in the watch, and fix the problem for good... Installing an ETA, while a partial solution, still requires the ETA to be serviced and maintained...add that cost to the cost of the ETA, the cost of the install, new hands etc...and you can get your Asian serviced 2 times or more, and get 10 years of use from it... This movement has been revied in depth, with service there is no reason for it to not last as long as any ETA... RG Quote Link to comment Share on other sites More sharing options...

RG yes yes yes considering it has to be opened no matter what scenario i select. that is exactly what i will do. so The Zigmeister we have to talk about servicing from NY/NJ.
