How can i make a tiled/striped texture on a sphere ? (see example below)

Hi, yesterday i got an exercice asking me to texture a sphere like the one presented on the image.

I never used texturing in Unity so I started trying things on my own and searching on the Internet about how I could do that. I ended up thinking that it had to be done with tiling and after some intents i made these 2 prototypes. For the left one, I just created a new material with the basic shader and I changed the values of tiling(we can see the tiles if we look carefully) and smoothness, adding a reflection probe aswell. For the second one i created a striped shader thanks to a tutorial.

The problem is that none of them make it, I don't know at all how i could do the presented effect. It seems like the sphere is composed of 2 different textures alternating with tiling. One seems to be a metalic texture that reflects the environment, and the other one the grey default unity texture.

Could someone help me, I have to send my work before friday and I'm a bit stuck at the moment.

Thank you in advance for your answers.
