Bignasty Posted June 6, 2006 Report Share Posted June 6, 2006 Hello all! So today I got a very special package in the mail for my very Speciale watch! But seriously. I got the Serie Speciale Navitimer from Trusty this past week. I've had nothing but bad experiences thus far with the Asian 7750 so I began my hunt for an ETA 7750. Found a new one for a great price, ordered, paid, and waited patiently. Well today I had a good day at the mail box, my new ETA movement had arrived! So I contemplated whether or not doing the swap myself. For the last few days I've been using old watches for practice and I thought "why not try to do this, might as well take the plunge!" So tonight after work I began the process. Needless to say the swap went well. Won't waste your time with words anymore. Here's the pics. I'm one step closer to doing some mods for you guys like this! My confidence level is slowly climbing. Also I'd like to thank all the members that have offered to send their old watches in for me to practice with! I will take care of you all when I get started with the mods! Cheers and enjoy the pics guys! Jon New movement looks nice! Another shot! Case back off, here's the old asian 7750. Rotor removed for easy handling. Movement out! Hours, minutes, and chrono minutes removed! Smooth sailing so far! Remaining hands and dial off! All down hill now! Comparison shot, ETA on the right. Dial in place, all hands installed! Oh yeah its coming together now! Movement in! Silicone grease to seal her up! Case back on and tighten it up! Finished product, looks nice, but more importantly runs better!

marrickvilleboy Posted June 6, 2006 Report Share Posted June 6, 2006 well done mate! u know what though...u can use the old asian 7750 movement's rotor with the breitling signature and place it onto the ETA 7750. =) Quote Link to comment Share on other sites More sharing options...
Bignasty Posted June 6, 2006 Author Report Share Posted June 6, 2006 well done mate! u know what though...u can use the old asian 7750 movement's rotor with the breitling signature and place it onto the ETA 7750. =) Yeah I thought about doing this, but decided against it. Doesn't really matter as I won't be taking the caseback off for anyone to see. I was more concerned with reliability of the movement here than the appearance.

discomonkey Posted June 6, 2006 Report Share Posted June 6, 2006 how does it sound compared to the asian 7750? I have an IWC GST with the asian 7750 in it and it sounds scratchy when the rotor spins. i'm not exactly sure how "smooth" a swiss movment is supposed to sound. do you mind if i ask you how much your swiss 7750 was?

Jetsons Posted June 6, 2006 Report Share Posted June 6, 2006 Excellent work and tutorai, Bignasty. Terrific step by step photos as well. You make it look easy. Now, that's a watch! Cheers, Jet Quote Link to comment Share on other sites More sharing options...
ubiquitous Posted June 6, 2006 Report Share Posted June 6, 2006 Excellent work! Great write up and images to illustrate the process! I think the Swiss ETA is the best solution to 7750 B1 woes Quote Link to comment Share on other sites More sharing options...
Craytonic Posted June 6, 2006 Report Share Posted June 6, 2006 What sort of deal did you get on the swiss 7750? Quote Link to comment Share on other sites More sharing options...
supermanx Posted June 6, 2006 Report Share Posted June 6, 2006 Did you debate putting the GEN dial on at the same time... this is probably my next project if i keep my breitling swiss with gen dial. Quote Link to comment Share on other sites More sharing options...
Bignasty Posted June 6, 2006 Author Report Share Posted June 6, 2006 Thanks for all the comments guys! The movement was brand new for less than $240 shipped! Movement sounds smooth but you can still hear it winding and rotating. Even the gen's do this. My old Super Avenger did it and my friends Chronomat Evolution did it too. Both of these Breitling Calibers were adapted from the ETA 7750. I thought about doing a gen dial but this is the Serie Speciale Navitimer which was produced in limited quantities. If I did the gen dial I would also need a different case back. So I stuck with the rep. I'll probably do these types of swaps for others with Gen dials if they request it and source the parts themselves. Cheers, JOn Quote Link to comment Share on other sites More sharing options...

Rolexman Posted June 13, 2006 Report Share Posted June 13, 2006 How did you safely remove the hands... did you use a special tool? Can it be done without a tool (using tweezers, screwdrivers etc)? Thanks Quote Link to comment Share on other sites More sharing options...
Guest TTK Posted June 13, 2006 Report Share Posted June 13, 2006 No....you can buy a hand removing tool very cheaply on the Bay.....do not use tweezers.....if you slip....potential for lots of damage.....! Quote Link to comment Share on other sites More sharing options...
JKTOWN Posted June 13, 2006 Report Share Posted June 13, 2006 Where did you purchase movement, Ebay? Or how did you source it ? JKTOWN Quote Link to comment Share on other sites More sharing options...
sammalone Posted June 13, 2006 Report Share Posted June 13, 2006 Ditto, great job, I would love to do this with mine, how did you source the movement for such a great price? Thanks Where did you purchase movement, Ebay? Or how did you source it ? JKTOWN Quote Link to comment Share on other sites More sharing options...
Bignasty Posted June 13, 2006 Author Report Share Posted June 13, 2006 OK couple of questions I see. 1. Yes you use special tools to remove the hands. Bought them off ebay. 2. Movement came from Ebay as well. Just type "ETA 7750" and you'll see them. There are several sellers with them from time to time.

Canuck88 Posted June 16, 2006 Report Share Posted June 16, 2006 I'd swap the rotors... won't affect reliability at all, and it'll look better. Quote Link to comment Share on other sites More sharing options...

Finepics Posted June 17, 2006 Report Share Posted June 17, 2006 I'd swap the rotors... won't affect reliability at all, and it'll look better. Agreed - they fit perfectly then you get to have the original as a spare if the bearings on the rep one ever wear out. Quote Link to comment Share on other sites More sharing options...
scoobs1971 Posted December 17, 2006 Report Share Posted December 17, 2006 Just bought the TAG Heuer Link Chrono as reviewed by By-Tor. It´s a beautiful peace of art and very accurate in the details. However, though I don´t mind hearing the rotor a bit - it´s also common for gens- this Asian 7750 is very, very noisy. Anyone knows if it´s possible to replace the movement with the ETA 7750? Will it fit in the case and are the dial spacings correct? Thnx! Quote Link to comment Share on other sites More sharing options...
slay Posted December 17, 2006 Report Share Posted December 17, 2006 what about the datewheel? you did not swap it, did you (do asian 7750 datewheels even fit siwss 7750 movements?) anyway, good job! Quote Link to comment Share on other sites More sharing options...
Pugwash Posted December 17, 2006 Report Share Posted December 17, 2006 Will it fit in the case and are the dial spacings correct? Yes, but the hands won't fit. Quote Link to comment Share on other sites More sharing options...
2005SUBMARINER Posted December 17, 2006 Report Share Posted December 17, 2006 awsome job ! i didnt know that eta 7750 was a direct swap fpr an asian 7750 would like to try this on a asian 7750 daytona Quote Link to comment Share on other sites More sharing options...
Devedander Posted December 17, 2006 Report Share Posted December 17, 2006 Very nice! How did you put the hands back on? Just tape and a pen or what? I thought the asian 7750 in standard layout was supposed to not be a troublesome movement? Quote Link to comment Share on other sites More sharing options...
