I have a leather cleaner and conditioner which i use to keep the leather moist. The Fauve is my favorite band but it's also in my opinion the most delicate but the other bands are resistive to issues.
Noir is nice because you can hide blemishes better. I just checked the Hermes store, i don't see the Noir - only if you buy the watch.
i got it via apple store app.. by selecting any other single tour band, there might be a noir option (black circle) if u look around the colour change selections..
See the second circle? it's not visible if u go to the watch strap main page..
