Thank you for sharing these. I, too, have an affinity for blue dials. I ended up with a 2016 Memovox Boutique Edition in blue, and have recently been considering a Geophysic. The Gronefeld and Kari are just dreams for me, but very nice dreams.
What a nice selection... perfect style and some horological heavy artillery! One piece to make this a quintet would be one of these stunning blue De Bethunes - think Skybridge, Starry Varius or the all-out Kind of Blue. Thanks for sharing! Daniel
