How to build a low beat Diver, or how to make a almost perfect rep a bit more...
Hi guys, since JF and noob make almost perfect reps of the AP Diver is there not to much to do for a good AP rep.
But as we know the AP 3120 is a low beat movement with 21.600 beats per hour. The most diver reps come with an A2824 movement with 28.800 bph.
So is the low beat mod one of the last mods you need for a perfect rep.
I have done a low beat mod and I will share that with you guys.
First step is finding a low beat movement.
I have some old swatch automatic with ETA 2840 movements.
The 2840 is a low beat and perfect for that mode because it's the same base as the 2824 high beat.
When I was younger I was a swatch collector and I had many of that watches.
But now they must die.
Sorry guys but I need your heart, but you can continue to live in a much much nicer steel body....hehe
Here is what we want...
So let's pull the 2840 out and take it apart
Remove all the bridges, wheels and springs and at the end we have a Swiss movement in parts.
Next step is clean all the parts in a ultrasonic bath
If that is done we need a new body for the Swiss movement and here comes the Diver into the game
I have here a Diver from a friend at the forum, build from the best parts available.
we start here with the same procedures as before, take the whole think apart
Case back
Anti magnetic plate
Next step is pull the movement out of the case
Remove the hands
And the dial
And as before, take the whole Asian movement apart
At the end these are the only Chinese parts we use for the new build
And here are our Swiss friends joining the party, freshly cleaned and ready to install
first we start with the keyless
Next step is the date wheel
Ok, let's turn this baby around and see what is at the other side
Nothing beats a fresh cleaned movement.....
Next step is the Swiss gear train
And the Swiss bridge.
Now I install the pallet fork and bridge. Sorry for the bad pic but I need much light for that step
I install the next bridge, the barrel bridge and wind up the movement a bit.
Well and now comes the best part for me... the heart.
I really love the moment when the movement starts to live.

Nice and slow....hehe
Ok, now we install the last bridge
And than the dial and the hands
And than back into the case
Greasing all the gaskets and push the stem back to the movement
Ok now it's time for the first check if all work fine
And yes, it looks pretty good.
Now we put back the rotor, I use here the AP rep rotor even if you can't see it but it's nice to know he is there
Cleaning the case from the old grease, screw the anti magnetic plate back to the movement and close the case back.
That's it, now we have a nice AP Diver rep with an nice ticking Swiss low beat movement.
One step closer to the gen Diver and now nearly a perfect rep.
I know some of you think now "why? You can't notice the beat rate anyway" but that is wrong.
You see the second hand move totally differently with 21.600 bpm.
And you can notice that for sure if you see the watch.
And you can also hear it.
I hope you enjoy this little inside and if you have any questions feel free to ask.
And one more think, after that mod your diver is not just closer to the gen, your movement is also...
Water resistant....I just love that Swiss guys...hehe
