A porcelain dial Omega wristwatch I recently stole - Any insight?

Hi everyone,

I actually intended to post about the watch when I receive it, but I will likely not receive it for a month at least and I'm just too excited and too curious. Case size was reported as 28mm including the crown

Reverse image search couldn't find a similar caseback, so maybe it's not even Omega - but the price ($100) I got the watch for is so low that it wouldn't upset me. I plan to service and wear this watch if I can, and if it's nothing special but original. If it turns out to be anything special I will likely not be able to touch it

Have you ever seen a similar watch / what could the era be?

And the ChatGPT analysis - I didn't tell the case was 28mm so I think it eliminates the conversion possibility

If the watch is indeed this old, would be cool to wear a 100 year old watch

Sadly most people I shown are repulsed by the case, no respect

The only thing more repulsive than the case is the chat gpt.

The cracked enamel gives me hope

Beautiful little watch, keeping good time, high amplitude, 1923 from the serial

Perlage inside the caseback but nothing written, however the movement / case and caseback fitment seems to be very well - is it possible the case is original to the movement?
