Well, I was bored and had some spare parts laying around and figured I would try a little experiment.
I used an old cannon pinion and hour wheel from an old 2834-2 movement. I also have a set of genuine rolex hands that I picked up cheap. They are scratched and scuffed and non usuable. They are also yellow gold so will not work with my project.
First off, here is a shot of the hour wheel. Original on the left, and modified on the right. Original diameter is 1.50mm. I modified the hour wheel to a 1.40mm diameter. This is to fit a genuine hour hand which comes with a 1.40mm hole size.
Next is the cannon pinion. This is from a 2834-2, so it is too tall for the 2824-2 anyway. Notice the top of the cannon is smaller in diameter than the rest of the cannon? This measures .90mm. The rest of the cannon measures .97mm
Here is original cannon pinion on the left, and modified on the right. I smoothed the modified at the top until it was .95mm in diameter. This is to fit a genuine Rolex minute hand that comes with .95mm hole.
So far so good!
I installed the modified parts in my modified 2824-2 movement. See post on my modified 2824-2 movement as this is now a two position non-date movement. Also notice the modified 'enlargement ring' from an eta 2834-2 movement. I am using an old dial that I picked up on the bay, I figured I could use it at the time, but it is far too scratched, and missing luminova fill. It is now used for test fitting.
I installed the hour hand. It Fits! Notice how the hand is slightly domed, and not flat or bevelled like rep hands. You can see it thin out on the edges. Very nice hands! Too bad I can't use them for the final project.
Here is a shot from the top. Notice how the tip of the hour wheel nearly touches the tip of the dial marker? I never noticed this before. Funny how you notice different things when working with genuine parts. The rep hour hand I have is too short now that I compare.
Next, I installed the minute hand. It Fits as well! It is hard to tell from this picture, but the minute hand is slightly domed as well.
Here is a shot from the top.
Again, these are not the parts that I am going to use for finished watch. These are only for test fitting and reference. They are too damaged for use, but they work great for testing!
The only hand that I was not able to fit is the second hand. The fourth wheel on my 2824-2 is .25mm, and the hole size for the genuine second hand is .22mm. Not a big deal as that should be easy enough to broach when the time comes.
Now if I can only find a mint set of genuine hands in white gold that are domed! So hard to find those hands. They are the only parts holding me back from finishing my franken EX-1.
One other note, the lume on these genuine hands is awesome. Obviously SL. I charged them up last night and set them on the night stand when I went to bed. They were still glowing (faintly, but still noticeable) in the morning when I got up. It was still dark out and they were still glowing after 8 hours. I had my genuine dial out as well for comparison and they match perfectly. Too bad the hands are in yellow gold.
Anyway, I would have to say my experiment worked! If you are looking at fitting genuine hands to your rep or franken, this is one option for you.
One step away from completing my ultimate franken project!
As always, your feedback or comments are welcome.
Cheers.
