Watchmeister Posted April 15, 2007 Report Share Posted April 15, 2007 Wow! Per usual, the work is stunning and as is occasionally the case I am the fortunate beneficiary on the EVO and the Pilot. Let this finally put to bed the myth of not being able to swap Swiss for the newer Asian 7750's. It just requires a skilled watchsmith. Link to comment Share on other sites More sharing options...
2005SUBMARINER Posted April 15, 2007 Report Share Posted April 15, 2007 amazing ! excellent work as always .. Link to comment Share on other sites More sharing options...
verbal Posted April 15, 2007 Report Share Posted April 15, 2007 Rob, great post, as usual, short question if you don't mind me asking; what did you do to make the center seconds hand fit.? Would love to know, I've had some great "fun" upgrading my Carrera, it all worked out well in the end but it was more luck than watchmaking skills.. and I'm planning on upgrading all my Asian chrono's.. TIA Link to comment Share on other sites More sharing options...
Watchmeister Posted April 15, 2007 Report Share Posted April 15, 2007 I think that request falls into the "secret sauce" category. More importantly it varies by watch and hand hole size differential. The "new Asian 7750 28800bph" is not one movement. It is made by at least three different factories so it will depend on the watch and who made the movement. I am with you on the upgrade concept. When I heard from Ziggy that any 7750 can be upgraded I picked up a dozen 7750's for a good price and over time will have Ziggy selectively upgrade my dozen or so favorite watches.

JJFlash Posted April 15, 2007 Report Share Posted April 15, 2007 Are those the old eta 7750 with seventeen jewels? Do they take the same size hands as the twenty-five jewel movement? Link to comment Share on other sites More sharing options...
RWG Technical Posted April 15, 2007 Author Report Share Posted April 15, 2007 The ETA 7750 series are all the same sized hands, 0.25mm for center seconds, 0.18mm for subdials...older or newer models. Yes, it's sort of a secret sauce for the installation of the hands from any newer Asian 7750's that have all 0.20mm hand sizes. I have a couple of things I do to get them to fit, nothing affects the future disassembly or servicing of the watch, I have yet to run accross any Asian 7750 powered watch that I could not replace with an ETA. A HBB should be on the way to me sometime in the next couple of weeks, and then I can put to rest the "rumours" of this one being non-upgradable...I'll believe it when I try it.

watchlover321 Posted April 15, 2007 Report Share Posted April 15, 2007 Keep us updated with the HBB, The Zigmeister! :D Link to comment Share on other sites More sharing options...
Watchmeister Posted April 15, 2007 Report Share Posted April 15, 2007 Given that you have done it with the Asian 7750 PAM 196 I suspect it will be very doable. Besides I would never vote against you when it comes to horological matters. Link to comment Share on other sites More sharing options...

maxmilian Posted April 16, 2007 Report Share Posted April 16, 2007 What are the price for this service The Zigmeister ? Also do you source the swiss 7750 or do you want the customer to send it along with the watch ? Finally ,done any Tag link chronos ? Link to comment Share on other sites More sharing options...
RWG Technical Posted April 16, 2007 Author Report Share Posted April 16, 2007 What are the price for this service Ziggy ? Also do you source the swiss 7750 or do you want the customer to send it along with the watch ? Finally ,done any Tag link chronos ? Price depends on the amount of work needed, if you have a old Asian 7750, with the 12-9-6 subdials, it's a easy swap, and takes about an hour ($50), if you have a new Asian 7750 12-9-6 then it's about a 2 hour job, if you have a Asian 7753 3-6-9 subdials, then it's a full service for both movements to move all the parts around, full service on A7750 is $200... I don't source the ETA 7750, Ebay has many, and Kruzer00 posted a link to a seller who has the older model, which is very well priced. I can't remember if I did a TAG link chronos...after a while, they all look the same... RG Link to comment Share on other sites More sharing options...
Watchmeister Posted April 16, 2007 Report Share Posted April 16, 2007 I can answer that one. You source your own movements. You can find them on the bay or with typical suppliers. I now buy fewer reps and then upgrade those reps which I think are keepers after I have received the watch. Cost of the movements is from $150 to $250. Ziggy will tell you what he charges for the movement swap. I would also add that I even do it on reps that come with a Swiss version. It tends to be substantially less costly, you know that the movement is in good shape, a watch at that price mostl likely deserves a relume and the watch is properly sealed and serviced by a trusted watchsmith rather than some bored person in a factory.

maxmilian Posted April 16, 2007 Report Share Posted April 16, 2007 Great info guys ! now I just have to save up some cash. I really would like swiss in my TAG Link to comment Share on other sites More sharing options...
watcher Posted April 17, 2007 Report Share Posted April 17, 2007 Great work The Zigmeister!!!!!! One thing I notice about the IWC is that you chose not to get the eta black day/date wheels to improve the font. All the same it looks very good and will last for a very long time now!
