musicale Posted March 12, 2008 Report Posted March 12, 2008 Noticed lots of reps now seem to be using the 7753, but haven't seen any Navis. Has anyone done this mod yet? Seems like it was make it more reliable and remove the datewheel problem. Would there be alignment problems with the case?
andreww Posted March 12, 2008 Report Posted March 12, 2008 Have never seen anyone try this mod unfortunately. Probably the cost of a 7753 is the biggest factor. On top of that you would need a genuine dial. Then you would still have an incorrect date wheel to contend with.
DuDro Posted March 12, 2008 Report Posted March 12, 2008 I've never understood why the rep-makers have not made this available?!? There is a small amount of DayLight chronos with 7753, but I've never seen a Navi with one...I'm sure these would sell much better than the PAMs if they were to be released. I personally would be interested...Perhaps we could pester Angus...Hmmm....
anton Posted March 12, 2008 Report Posted March 12, 2008 If you implanted the 7753, you would run into the following problems: 1) you would need genuine hands. these are nearly impossible to find. 2) genuine dial. seen some on eBay, so it's not that big of a deal. 3) you would lose the quick-set date function. and the way it is modified on the gen tricompax models is that the date change function is used by moving the hands back and forth between 8pm and 2am until you reach the desired date. Some have said that the tricompax navitimers are based on a 7750 w/o a quickset function. Others have said it's based on a 7753.
andreww Posted March 12, 2008 Report Posted March 12, 2008 Hands can be used from a 1st gen rep Anton. Like you said, dials are available, but they are slightly too large for the rep case. The can be filed down, but much of the slide rule "tics" are hidden under the insert. Date change is a problem, yes, but most could live with that. Biggest problem is the direction of the single digits on the datewheel. I've never seen a solution for that.
Seadweller4000 Posted March 12, 2008 Report Posted March 12, 2008 Are dialfeet on asia 7753 differently located than on gen ETA?
andreww Posted March 12, 2008 Report Posted March 12, 2008 I believe dial feet are the same from 7753 to 7750. After all, I've seen gen dial installed on the asian 7750 tricompax (which is 7750 based), so there shouldn't be an issue with that.
Seadweller4000 Posted March 12, 2008 Report Posted March 12, 2008 Thanks mate... Just got confused as some stated one would need a gen dial for ETA 7753 swap...
LegendofSpeed Posted March 12, 2008 Report Posted March 12, 2008 hmmmm..... as i started reading this topic i was thinking about swapping out the movement from my 7753 188... then my hopes died...
andreww Posted March 12, 2008 Report Posted March 12, 2008 Thanks mate... Just got confused as some stated one would need a gen dial for ETA 7753 swap... You would need a gen dial, but not because of the movement so to speak. Its because the date window on the 7753 is more outboard then on the asian tricompax. You could use the rep dial but the date would be shifted way to the right.
yellomen Posted March 13, 2008 Report Posted March 13, 2008 gen dials are not that hard to find... maybe i even have one somewhere. If you're interested i could check my parts box.
Rxus Posted March 13, 2008 Report Posted March 13, 2008 It's such a shame the same factories that produce the A7750 haven't come up with a 7753, it would allow a lot of rep that are released to have the correct movement and the DW issues that all those tri-compax watches have, which is the sunken Date. If all else fails get your hands on a 6,9,12 Navi It's what I plan to do
