Zurks Posted October 2, 2015 Report Share Posted October 2, 2015 Hi Guys,I recently got a rep 3717 to see if I'd like it, but now want to put a swiss 7750 in it. I'm looking for a modder to do the work. I saw some mention of Concepta, but don't know how to contact him or even if he's still making those mods. Anybody have any leads or suggestions?

tomhorn Posted October 2, 2015 Report Share Posted October 2, 2015 Concepta is gone, and even if he weren't, he wasn't the modder.Keep in mind, the A7750 hands need to be modified to work (unless you have a very old 21.6k movement). Also make sure you use the ETA day and date wheels.In the US, you have several choices. Personally I would reach out to to member "misieped" and see if he can do what you need. PBDad is another choice, but he has an outside watchsmith that would probably do the work (which means it could take longer), or go to Vaccum (aka Vac's Modification Shop) if you also want the dial re-lumed, 1 Link to comment Share on other sites More sharing options...
Zurks Posted October 2, 2015 Author Report Share Posted October 2, 2015 Thanks Superposter! I found a gen dial I may get too, but will it work on a7750 or just the swiss version? Link to comment Share on other sites More sharing options...
imajedi Posted October 2, 2015 Report Share Posted October 2, 2015 Gen dial will work with either Swiss or Asian 7750 but as Tom mentions you need the hands to match the movement or will need to mod the hands to fit 1 Link to comment Share on other sites More sharing options...
Zurks Posted October 2, 2015 Author Report Share Posted October 2, 2015 Will Gen crown/tube work with a7750 or just swiss? I just found one of those too. Link to comment Share on other sites More sharing options...
Guest Posted October 2, 2015 Report Share Posted October 2, 2015 Will Gen crown/tube work with a7750 or just swiss? I just found one of those too.Gen crown/tube works with both a7750 and swiss because they both fit with the tap10 stem.However, a gen crown only works with a gen tube (inside thread). Conversely, a rep crown only works with a rep tube (outside thread). Link to comment Share on other sites More sharing options...

Guzziguy Posted November 15, 2015 Report Share Posted November 15, 2015 I'm just getting into the rep world and I'd like to know what it costs for a Franken IWC 3717. I'm buying one from a TD and if I like it I may want to at least convert the A7750 to an ETA or Valjuen.It sounds like an interesting project. I'd like to start out buying one and then learn the craft myself.Thanks for any advice or insight.Thanks! Link to comment Share on other sites More sharing options...
ck5533 Posted November 16, 2015 Report Share Posted November 16, 2015 However, a gen crown only works with a gen tube (inside thread).

ogladio Posted November 16, 2015 Report Share Posted November 16, 2015 Gen crown needs a gen tube. I'm just getting into the rep world and I'd like to know what it costs for a Franken IWC 3717. I'm buying one from a TD and if I like it I may want to at least convert the A7750 to an ETA or Valjuen.It sounds like an interesting project. I'd like to start out buying one and then learn the craft myself.Thanks for any advice or insight.Thanks!Depends on what gen IWC parts you wish to add. Cost for crown and tube you can see via link above. Dial, hands, datewheel etc will add some extra $$$ - if you can source.A fresh ETA 7750 should be about $400, if buying used you might need to add funds for service. If you want a gen IWC movement instead ("7750 based") that should be up to $1000. Note - imo there's nothing wrong with the a7750, given I can use money for something else instead.As always with frankens, there's really no limit to what you can spend - after some time collecting you might realize you've spent more than a used gen costs...

GBOGH Posted November 16, 2015 Report Share Posted November 16, 2015 Where can you find an OEM movement for the IWC 3717, sold by itself? Link to comment Share on other sites More sharing options...
ck5533 Posted November 17, 2015 Report Share Posted November 17, 2015 can anyone tell me please..........does the rep case needs any modification before it can be swapped with a gen movement and gen crown (with gen tube of course)?? p.s. sorry to jump on your thread but I'm on the same route as you.

sacsah1 Posted November 17, 2015 Report Share Posted November 17, 2015 No it doesn't. Given that the 79320 is modified 7750, it shouldn't require any modificationsSent from my LG-H901 using Tapatalk Link to comment Share on other sites More sharing options...
Guest Posted November 17, 2015 Report Share Posted November 17, 2015 Back in the day when gen parts were relatively available a franken build (gen dial, hands, crystal, datewheel, crown, tube, ETA 7750) would cost $1700 - $2000 to obtain. Now the parts aren't accessible except maybe Scotchwatch (since his prices are insanely inflated) it'll cost much more. Link to comment Share on other sites More sharing options...
ck5533 Posted November 18, 2015 Report Share Posted November 18, 2015 the biggest tell of all is the crown based on my research. Lately, someone over RWI told me there is a V6 3717 on the market, I donno how good is that.Has anyone bought one recently? don't mind to share.........

No, no modification is needed to fit in an ETA 7750 or IWC 79320.

Great info. appreciated. now which TD has the best version of 3717-02 (white dial)?I like this than the black dial simply because there are rare and classy especially with tan/brown leather strap. Look around your collection I am sure 90% are in dark/black dials. Link to comment Share on other sites More sharing options...
higginsd Posted December 1, 2015 Report Share Posted December 1, 2015 All TDs have the same 3717-02. Hopefully they have the 3717-02 still in stock or can get this version. Link to comment Share on other sites More sharing options...

However, the Asian centre secs can normally be broached to suit the ETA, so only the sub dial hands are needed. There is an Ebay source for these which I am going to try for mine, which has an ETA 7750 already. Link to comment Share on other sites More sharing options...
