Welcome to the forum.

After looking at Miyota's technical drawings, I'd be surprised by any case that works with (say) a Miyota 8205 but cannot be made to work with an 8N24. All the dimensions that matter are the same or nearly so. (The 8N24 is a bit thinner than an 8205, which is the safe direction.) Case clamps are the same. Some cases might assume you have a plastic movement ring that fits your movement and the case.

For the 8N24, you'll need a no-date dial. The 8N24 accepts hands with the same hole diameters as 8xxx, but you'll need to pay attention to the hand length (as you would with any other 8xxx series movement).

 

Thank you so much for your reply! I will pick up a case and give it a try!

As for the movement ring, I believe the case comes with a movement ring. Shouldn't be too difficult to design and 3d print one to fit the 8N24.
I'm plan to use a dial from DIY watch club.

I will try to post my findings back here, I know there are a lot of people asking questions about cases...
Any other thoughts are welcome!

 

I'm back, I want to answer my own question... SPOILER ALERT!!! NEVERQUITESURE was right...

One thing I didn't consider while picking parts, the dial I picked is curved. It interferes with the movement ring. The case was made for a flat dial, so pay attention for that if you're reading this and are picking parts. It really screws up how everything is supposed to sit inside the case.

I used a case from aliexpress, it was 41mm in diameter.

The DIY Watch club dial was 32.77mm.

Curved dial or not, I was able to make everything work as I hoped. It took about a month of tinkering after work, and about 25 different 3d prints.
I had to design a movement ring that would accept the curved dial. It took a few prints to get everything to perfect fit, as I didn't want to file much. I also lack tools to measure such small distances with any accuracy. Another issue was 3d printers don't like to make accurate inside diameters without tinkering...

I had to print a spacer that went between the case and the dial, this was done to align the winding stem with the hole in the case. The curved dial made the movement sit too far down inside the case, a new movement ring wouldn't do the job on its own. Not sure if this is because the case was designed more for a 8200 movement, and the 8n24 is thicker?

I printed everything on an Ender 3, .2mm nozzle, .12mm layer height.
Hope this helps someone down the road!

 

Yes, it does help someone. Thanks.

 

I doubt that Bennie121 will respond. The last time that he stuck his nose in here was 3 years ago.

But good luck anyway.
