So, I finally got my LeftHeart, and i'm working on breeding a Passion dragon with a lvl 4 LeftHeart and a lvl 4 RightHeart. I got sooo tired of breeding Magic dragons, that I bought some gold to speed up the process.

Anywho, I'm not sure how many times this happened, but on what I think was the 8th or 9th try, I bred a 13 hour clockwork dragon The result wasn't in any breeding calculator I could find, and i'm not sure how this happened, but i'm not complaining! Clockwork has been eluding me for about a year now.
