Wondering what do you mean by not getting enough love?
You mean it gets less recognition by the generic public... than, say, the
Zenith El Primero, Omega 321, and the Rolex 4130, for instance??
I kind of don't mind it being a "best kept secret" myself. I think the above
movements sometimes have been hyped up too much.
To me though, the 89360 series of movements are getting a lot of love (from
me). I have a number of IWC watches equipped with this series of movements,
ranging from Pilots, Ingenieurs, Da Vinci and Portugieser (Yacht Club). I
love them all.
