Super early... First one I've seen of these in yellow gold. In regular eyesight it actually looks a way better yellow gold.
Dial is super cool with its own gold gilt engraved ring.

Looks like we have one in the database as "Unknown".

Different case style.
I'm curious if this was originally two-tone or has been worked on. Looks amazing all the same.
Looking at the case serial number within my database I'm placing this at 1922/23.
Hrrrmmmm speaks to a white gold 25 Year (gold plated) with 16 Jewels, as the "Lady Maxim"?

Your watch has a different case shape to the above Lady Maxim.
Very cool in the two-tone. I agree it looks like the 153 like this one https://mybulova.com/watches/1923-153-12241

1923 Bulova 153 looks to be a good match based on the ad referenced in the other listings.
Very interesting watch, I love the dial. Question: the case looks like it is two tone with bezel front showing as white with engraving yellow. It almost looks like the bezel front may have been mechanically polished removing the yellow plating and leaving it in the recessed engraving? No matter, it's an exceptional looking watch that seems to be a case ad match to
