Hour wheel/cannon pinion

[Vonn]

Say I sourced some dials (river 3 piece).
Never had three piece dials before, only the usual one piece PAM dials.
Was pretty bummed when I saw that the A6497 movements I ordered came with H2 cannon pinion/hour wheel which are obviously not high enough.
Now before I order a set of H3 parts (wich cost about the price of a Asian 6497), will they fit the river 3 piece dials?
I’m gonna build another 44mm mini fiddy for wich I already have a (rep) OP XI movement for but I want to be sure that if I order three sets of parts, I can actually use them. Not sure if I’ll use the NW three piece or two piece dial yet.
As I’m still studying, going all the way with the 150$ hour wheel mod is not an option.
Or is the best option the tall barrel hands? IMHO they are too long for the 44mm case compared to the size of gen hands.

You can order tall tube hands from Athaya.
Hr hand is fine.
Min hand is that bit too long for a 44 mm build.
But there is hope.
Either bend the tip (stylish and as seen in some Vinatage Pam) or carefully cut the tip with a clipper.

Last option: you try to glue/solder tall tubes from Athaya to your hands. I guess this is tricky...

The mini fiddy uses a 36.5mm dial, so it’s like a 45mm Radiomir and Hand size is not such a huge issue like with a true 44mm case. But I’m more worried about the height of the wheel/pin.
So I understand you correctly that using the three piece dials I will need tall tube hands even if I use H3 pins?
Might sound a little dumb for someone with more experience, but will the combination of H2 and tall tubes work?

Sorry, it's complicated.
With a 45 mm RAD and a 44 mm MF case you will only be able to use 0.8 mm thick dials. For the MF there might be the option for a custom two piece bezel to make it accept a thicker dial. You may try Neckyzips or Nightwatch.
Only certain three piece construction 47 mm Rad cases will accept three piece dials. Athaya or Nightwatch for instance carry them. Rivers 47mm only take the 0.8 mm thick dials.
The 47 mm cartel cases will not accept 3 piece dials out of the box either. But Nightwatch is selling a 2 piece bezel to mend that problem. Then a 37 mm 3 piece dial would fit.

H2 is tight with 2 mm dials and long tubes, H3 is better. But the tall tubes will work with it and a 0.8 mm thick dial. However, you have to shorten the tubes. Just stick a modified toothpick in them and grind slowly on sandpaper.

Hot damn.
Knowing that, the beautiful 3 piece RP dial I just got from fellow member tafari will wander into the parts drawer.
Anyone tried to fit a three piece dial into the river case? I’m not confident with getting soldered lugs and sewing in a strap, too much of a fashion fictim here.

River selling 3-piece dial for 44mm case?
Hmmm interesting, gonna check it out.

3-piece in a 47 mm 3646 case from River will not work. It is only for one piece (0.8mm thickness) dials.
I can't remember how it is with his other cases. Perhaps another member can chime in here.

Don’t get me wrong. The 3-piece dials won’t fit a 44mm Lumi (they have 34.5mm dials). The mini fiddy uses a bigger dial than the standard 44mm Luminor case. I was hoping a ground down 37mm dial will fit a mini fiddy, as they will take a dial with up to 36.5mm diameter (depending on the maker). Didn’t know about the height restriction though.

I wonder why rivers high bezel case won’t fit a 3-piece dial and if using a NW/Athaya bezel would fix this issue. I can see why the low profile Cali one won’t fit, but the high bezel should have enough space.

Sorry for noob-crap-posting but getting knowledge in the field is kind of obstructed due to the broken old HF where lots of this stuff was already posted but in not accessable.

Yes, you can grind down a 37 mm dial to fit into a cartel 44 mm Mini Fiddy. But the height issue remains, unfortunately.
The way the bezel is made, there is not enough space to accomodate a thicker dial and screw into the movementholder at the same time.

Never mind the questions. this is why we have the forum
