Horological Meandering

It's a triple calendar moonphase in 18k rose gold I believe, but not sure what specific model. Looks very similar to a lot of celestographs from the 1950s I see online, but the sparse markings around the moonphase dial are unlike any I've been able to fin...  

I'm skeptical of both the dial and (seemingly mismatched) hands. Regards, Tony C.
