The Goldpfeil Vianney is more than double the price of the RM005...gasp...yes!!!
This is because the entire watch has literally tons of handmade artifacts...eg: the ballpein hammering of the surface, the crown, the complex curvatures of the case body...
The movement is built from ground up, and is a rectangular jump hour with quite an accurate moonphase, it has a rachet system built into the crown to give it the "film advance" tactile feel.
The hands and dial need to be seen to appreciate the depth of details and the 3d quality of the minute and seconds hand.
The moonphase is adjustable by turning the crown the opposite way...
Less than 108 exist, probably the costliest project made by the company and the man.
The Classic, is the price of a Lange 1 Moonphase...ball park.
The Antiqua is the price of an RM004...ball park.
