Let's start from the premise that the domed option is not as "mirroring" when the watch is under water and does not offer a clear view when you look at it from one side, unlike the flat option. Respectively, I resonate more with flat crystals. It doesn't distort the image (which is bothering and confusing) like the doomed ones. In addition, in sunlight, the doomed is not able to capture the light as flashy as the flat one.
And honestly speaking, I don't think it's different resistance between these 2 types matter that much. So, let's admit that the watch face (the watch crystal I mean) is so small that the pressure does not necessarily fall on it when the watch is under water. How many of you actually dive to great depths with your watch? especially if it's about a replica that resists (or maybe doesn't resist water at all) up to 25 meters?! I'm not referring to the divers professionals of course, but to the mediocre population here. And I'm not against watches up to 1000 meters absolutely nothing, except that I don't think anyone really tests this depth in watches, considering the human lungs simply explode at this depth, not to mention the watch.....
in short, I am for the flat type from an aesthetic point of view. as for functionality, I don't dive more than a meter under water, so the visibility under water really doesn't interest me
