The ZW is the perfect watch for the Lumen family. I got a chance to see the original Phantom at a Lange event, and I was blown away its beauty. Congratulations on your new addition!
I concur with the idea of a Perpetual Calendar... Or maybe a ZW Decimal Strike if you can find one. And you can't buy any new pieces or just no limited edition pieces?
What a special watch! I'd love to add a watch in the Richard Lange family to my collection one day. I especially like your Pour le Merite, and I am a fan of the Jumping Seconds as well.
