Hi, im new here. I've been trying to recognize this watch movement, but I can't. It's a Mercedes-Benz watch, bought in Italy and maybe made in Italy. It's automatic,
and it features an extra 24hrs dial, and power reserve (Riserva di carica in Italian). Here are some photos. The only logo I can see is that circle with horns. Please help me recognizing this movement.
Here are some photos, and a drawin of the logo
