Sounds like everyone is going two-tone. I agree it looks great. Only comments/suggestions I have are about what other jewelry you wear and price.
If you wear yellow gold and want to ensure your watch coordinates, then two-tone for sure. But if you wear white gold/silver/platinum, steel would be more seamless. Re: price…the steel is less expensive so that might be a factor, and the difference might allow you to get another piece of jewelry
I find the Panthere in two-tone is interesting….from a distance it’s hard to discern it even is two colors. The contrast just makes it pop a bit more but is very subtle. I’ve been watching “Buying Beverly Hills” and I think Alexia Umansky wears a two-tone Panthere but it’s very hard to tell, whereas another person on the show has a two-tone Rolex and the metal colors stand out very obviously.
