Fantastic little watch indeed. I really like the look, and the little increase in the all-round dimensions might also be a one up over the F91W for some. The extra water resistance is really nice, and it's the only model I've seen with it.
I'm personally not a fan of hooded lugs like on this W86 or G-Shocks in general, hence why I went with the F105W, but that's probably just me.
The startup business for educational clocks filed to trademark "Oyster and Pop". Filing to trademark something comes with a time to oppose, meaning anyone who thinks the trademark should not be approved for any reason can come forward. After which the court will look at the opposal and either approve the trademark or not.
Rolex thinks it infringes on their existing trademark and thus opposed within this period. It's up to the court to decide if they are correct or not.

You might see this as bullying, you might see this as Rolex protecting their trademark, but before choosing sides it's important to understand the legalities.
