Here's his step-brother from the same mother.
I believe this is a Fricker case.
The AquaLuna looks to be a fine watch, but I believe that Eric is correct.
If you go to Anders' website(Gnomonwatches.com), and look at both the Vortex and the now sold out limited edition Flieger Timer, you'll see that both models have "Made in Germany" clearly printed at the bottom of their dials. In the description section of both models, Anders clearly states that the cases(and watches) are manufactured in Germany.
If you look at the description section for the AquaLuna, Anders mentions that the case is milled from 316L using CNC technology, with no mention of German case manufacture. There's no "Made In Germany" on the AquaLuna dial, and, on the case back it simply says "Swiss Automatic Movement".
Again, I think the AquaLuna is a really nice watch(though the dial isn't quite to my taste), so no criticism or disrespect intended, but I believe that Eric is correct in his assertion that it's not manufactured by Fricker.
Here's mine on a oiled Panatime.
