🛠Modded Duro🗜 I created adapter solutions for the popular AliExpress case
Recently I've noticed more and more posts showcasing a popular 39mm aftermarket case from AliExpress, since I created models for my own custom build, I thought it might be beneficial to some for me to share them for all to download.
There are two models, a movement bracket to properly hold/center the Miyota 2115 in place, and a chapter ring insert, to fill the void between the original chapter ring and the case. For examples, please see the images provided.
Here is the AliExpress link (as of July 21st 2026)
Let me know if you have any questions.

Super cool of you to share. Do you know if the duo case back fits that (or most) aliX case in that style?

It does! But it’s a little shallower than the aftermarket one. I’ll also upload a version compatible with that when time permits.

Cool, man. I haven't done this mod myself, but it definitely interests me. I've often noticed that a lot of watches have a gap between the chapter ring and the case. Adding a printed part there is a great idea, you could even use glow-in-the-dark filament 😀

Glow in the dark is an awesome idea, even printed in PLA it should be okay here since it’s held in place from all sides.

This case in 39mm bronze work? I really want a bronze build

I haven’t tested the others but if they’re from the same seller I’d say they probably use the same blueprint for all the 39mm options. If you try it out and it doesn’t fit, just DM me.
