Well, marketing does what marketing does. In order to justify their positions and salaries, the marketing team in each company has to do at least "something". So, they chase trends in design and verbiage.
Currently this translates into enormous images of watches in some sort of "setting" (in the case of Zenith, it looks like a workbench, Omega showing the video game watch within an animation, Rolex the same) and what little text there is has to be searched for. This is because:
A. The vast majority of website visits are done on a phone (small screen).
B. Most people buy on "image" / how something looks / they think will make them look, not on quality (same for wine, people buy the label).
For Omega, they seem to be split between people who are younger and play video games (007 First Light Speedmaster) and people who think the watches used 60+ years ago in space / the moon landings are still "cool" (I would venture that these people are older). It is, I think, a confusing brand for many people.
If you are looking for intrinsic value, luxury watches are not that. They are jewellery.
