Best Nomos models for women?

I'd like to buy my sister her first mechanical watch, and seeing how I've enjoyed my Metro so much over the last 6 years, I was thinking it would be a Nomos.

I'm thinking of the pale orange-ish Tetra, the orange/coral Club or the champagne minimatik. The minimatik appeals the most because it has the 3001 movement (I believe the other two use alpha?) but wondering if this is something I should even care about, i.e. are all their movements basically equal at this point in time?

Also, curious what other watches (can be Nomos or other similar brands) you'd suggest for a woman. My sister likes pops of color, but I think subtle is better for a mechanical watch, especially if it's your first and it will be your daily driver.
