Mother-of-pearl takes the lead
The natural mother-of-pearl dial gives this reference its changing surface. Pale areas catch the light around the hands and stone-set marker appearance, so the face reads differently as the wrist moves. The effect is most useful in a 31mm watch: the bright dial opens up a compact case without needing a larger diameter. A magnified date at three o'clock keeps the Datejust layout recognizable and practical.
