is tourbillion even a real material? i've literally never heard of it before this

It's a part of the watch. It's really cool!

Tourbillons are the rotating cages they put the ticker in to even out the effect of gravity, so you get tickticktick, instead of tick,ticktick,tick,ticktick They’re considered luxury now. I bet these are fake, & the movement is quartz regulated (and loses a minute a day)

It's mentioned above that the tourbilon is the spinny thing on some watches, but there's also "billon" which is term for alloys that contains some less than 50% precious metal. The "war nickels" made in the US from 1942-45 were technically billon.
