For me this is a "grown" design after the twenties. The only one what reminds that there is design, are the long lugs and may be the bezel.
Patek was not the only house who had this case, i have a LONGINES of this years with the same case. I have seen Vacherons in Calatrava style too and others.
My Longines, now my mother wears this watch every day, is from 1935, 18 kt. gold and 31mm. You can observe the long lugs in relation to the case.
I dont think that the design in this years was an important thing, first of all the case were to protect the movement.
May be what we call today design, was the time waste and sometimes we can see some elements of art directions like ART DECO.

Dear Emil, excuse my late answer, i was five days off line.
I think it is difficult to answer, because you think it is Bauhaus, I think it is coincidentally.
I understand, that you will tie up Calatrava to the flat bezel, but Calatrava also had other bezels. The picture today in the forum helps me to explain this.
I know that Patek, Longines, Omega, Vacheron, Audemars had so called DESIGNER CASES like the Canape´, Tour de Eifel, Top hat, and more, but the old Calatrava in my opinon has a case, not more. So if you say, this is Bauhaus, a shoe polish dose also is Bauhaus. Also you can say, if their is no design, it is Bauhaus. But in this case, the lugs from Calatrava are too stylish.
Two fotos of Designer Cases. The Longines is pure Art Deco and PP is something like Canape´.
