Where can I find a ETA 2842 Replacement Case (No Date)

Hello bros,

I recently bought my first automatic. A Swatch Diaphane Irony from 2004.

It came in a disposable feeling plastic case and I am looking for alternatives. I want a case that will look great on a NATO strap.

Are ETA 2842 and 2824 cases cross-compatible?

I am looking for Aliexpress listings, but offers from other sites can still be useful.

Thanks in advance
