Patek Philippe Ref. 3858
I thought I didn't like this Golden Ellipse ref. 3858 powered by cal. 215, which I found odd.
But then I discovered this variant with a two-tone dial and I'm not sure anymore: I'm starting to like it...
I'll let you judge if the charm works for you.
You can even compare below with a regular Ellipse ref. 3748.
Best, Emmanuel
1/ Ref. 3858/1G (white gold case and bracelet, two-tone dial)
2/ Ref. 3858/1J (yellow gold case and bracelet, two-tone dial) NB: this yellow gold variant (with a slightly different bracelet) was mentioned here 16 years ago by
mpreddert.

4/ Ref. 3748J with similar two-tone dial as ref. 3858/1G and J
The Certificate of Origin describes the dial as ‘bleu, zones sans index’ (blue, areas without index), the original receipt from 1979 describes the dial as ‘cadran bleu clair, bleu foncé’ (light blue, dark blue dial) and the Extract from the Archives states ‘two-tone blue dial’ (cf. below).

5/ Cartier Ceinture with a two-tone onyx-turquoise dial : I'm adding this one just as a side note, to show that this sinuous way of dividing the dial has been used by other brands
