As for the movement, I am currently figuring out which cannon pinion, hour wheel, and seconds wheel did the 3131 used. According to ebay/ google search, the 3131 movement used 3155 seconds wheel. I am therefore inclined to think that the 3131 also used 3155 hour wheel and cannon pinion.
Some updates. It turns out my research and experimentation was true. I can use 3155/3185 cannon pinion and seconds wheel (same part numbers) to fit gen milgauss hands. To save cost, I extracted the cannon pinion and seconds wheel from a donor VR3185 movement.
I still need to order a gen 3155 280 hour wheel before I can install all of the gen hands.
The stock VR3131 movement died on me.
I ended up building a custom movement to mimic a 3131 movement:
- SH3135 base movement (with all the date components removed)
- VR3185 cannon pinion (complete 270 + 335)
- VR3185 seconds wheel
- VR3185 automatic module
- Gen Rolex 3130 230 setting lever (to remove the phantom date position)
- Gen Rolex 3155 280 hour wheel (i still need to order this)
My converted movement (without the taller 3155 280 hour wheel. The current hour wheel is the stock 3135 280 hour wheel. Note the taller cannon pinion and seconds wheel, which are both from a VR3185 movement):
Test fitting the gen dial and converted movement with the anti-magnetic cage to see if the cannon pinion and seconds wheel are tall enough:
Test fitting the gen seconds hand to see if there is enough clearance for it to move beneath the gen crystal/gen gasket.
The next step is to order a gen 3155 280 hour wheel before i can fully assemble the watch.
@pompompurin glad you could finally get this going! Did you end up getting the newer 3131 clone and still had this problem?
I think the vr3131 movement is more or less the same as the vr3130. I think they both have the same cannon pinion and seconds/hour wheel height. In order to use gen milgauss hands, modding is needed to elevate the height of the cannon pinion and seconds/hour wheel.
Assuming the stock GMF vr3131 movement doesn't crap out, you can probably get away with just replacing the following parts so that you can use gen milgauss hands:
- VR3185 cannon pinion (complete 270 + 335)
- VR3185 seconds wheel
- Gen Rolex 3155 280 hour wheel
(as always ymmv. I have the best luck by modding the SH3135 instead).
GMF has antimagnetic cage?
Yes, it does like gen (but don't expect it to perform like a genuine milgauss' antimagnetic function)
Hi guys,
I'm glad I found this thread. I am currently planing to (let someone) build a Milgauss Frankenstein as well. I managed to find a restored gen blue dial on ebay, as well as gen hands and a (non gen) green saphire crystal.
Now do I understand it correctly, that no matter if I chose BP or GM with either an A3131 or an VR3131 as a base, I will run into the problems described where the hands don't fit? I am not at all a watchmaker so please confirm ;-)
Someone suggested to me that I could also VR3130 movement and get rid of the date wheel. Does anybody know if that fixes the problem?
Also, are the cases of the BP and GM reps any different in dimensions and quality? Or doesn't it matter which one I'll get and it all depends on the movement?
Thanks in advance for any help =)
I owned an old BP milgauss with sa3131. Same problem occurred to me where the cannon pinion and seconds/hour wheels are too short for gen milgauss hands.
The stock VR3130 have cannon pinion and seconds/hour wheels that are also too short,
I read that the BP milgauss is made with 316l steel (and comes with sa3131 movement, although BP might have upgraded it to vr3131 by now if it isn't discontinued), whereas the GMF milgauss is made with 904l steel.
they are putting vr3131, but no idea about what I can do for a plug n play frankening..
If you don't plan to franken the GMF milgauss with gen hands, then maybe everything else is plug-and-play. However, the stock GMF milgauss tube doesn't look the same as a gen 7320 tube, so i have no idea if the stock tube can take gen 724 crown.
