In the vein of serious rotor-heads, have a look at this:

Rotary engine inspired watch "Experiment ZR012"
And available for the low, low price of only $114k $USD!

Just something to break the monotony of diagnosing mechanical issues on our 30+ year old cars!

 

114k? or 114$ ? it looks absolutely awesome. had to re-design the watch. but not worth 114k.

 

It's $114,000 USD. If it was $114 I'd already own one

 

Ballers don't appreciate engineering, know your market!
