Hi everyone, it's me again with another tutorial!
Today I want to show you my latest attempt in watch movement thinkering: a slow beat PT5000.
There are some info around on the various forums, but I want to agglomerate everything here for future reference.
Disclaimer: everything I am about to show is done by an amateur watchmaker (me) and before attempting anything you should decide if you are willing to take the risk and if your skill level is enough not to mess up everything. What works for me might not work for you and viceversa.
With that being said, let's start with the tutorial!
Currently the only three options for a slow beat 2824 are either the crappy china clone sold for around €20 online, an old ETA 2451, or an ETA 2842 from an old Swatch.
The problem with the latter option is that the mainplate does not have dial feet holes and is also lacking the threads for mounting tabs screws, so the solution is to either drill those or change mainplate with an ETA 2824 movement.
The 2842 is simply a cheaper version of a 2824 with a 21600 bph frequency and a lower number of jewels which are instead replaced by plastic bushings. The idea of having plastic in my watch is something I have never really liked so a transplant is what I came up with. In fact the only parts that differ between the two movements are:
-Balance complete (Part #721)
-Pallet fork (Part #710)
-Escape wheel (Part #705)
-Barrel complete (Part #180)
Let's now talk about the "receiver", a PT5000 movement which is most likely the best chinese ETA clone I have ever seen. In all honesty I wonder if some Swiss 2824 clones are just rebranded PT5000... Ok enough gossip, here a pic of the movement, which you most likely already know:
The "donor" will be taken from an old automatic Swatch that I bought online for around €20, similar to this:
Here the infamous plastic bushings found in the Swatch movement:
To disassemble the movement you can follow this tutorial:
Once the movement is disassembled just take the parts listed above and set them aside. Repeat the process with your PT5000.
Now we can assemble the PT5000 and use the stolen parts from the 2842:
As you can see the finish of the bridges is slightly different, but is good enough for me.
Additional tip: if you want to remove the ghost date position of the crown you can transplant the Setting lever spring (Part #445)
Aaaand here you have it! A perfectly running PT5000 which beats at 21600 bph, perfect for your vintage builds!
The movement still needs to be properly serviced as I wanted confirmation that everything would work before proceeding; I will keep you guys updated with final performance once I find the time to service it.
Thanks for the attention and feel free to ask questions if you have doubts or need clarifications !
