Omega watch calendar frame is not three-dimensional, is it fake?

Authentic Omega watches have a full dial logo, and the calendar box at three o'clock is very layered, while the logo of fake Omega watches is flat, and the calendar box does not have the layering that genuine watches should have.

Omega is a Swiss watch brand, which belongs to Swatch Group and was founded by Louis Brandt on 1848. Omega watches have four series: Constellation, Hippocampus, Motorized Altman and Disc Flying.
