My Other Watch Is...
44
Extremly handsome watch and a great photo of it.
Your comment about it being a Kurt Klaus classic prompted me to share this one:
Herr Klaus really hit the ball out of the park with his invention of this perpetual calendar movement. I have several other QPs that all set with pushers, and I dread having to reset them after they have wound down. For any readers not familiar with them, the calendar is set using only the crown; no pushers!
If you compare these 2 watches, you can really appreciate the breadth that IWC covered with this unique movement.
