And for odd months that don't fall int 30 days, you are going to have to reset the date complication.
They were better off going digital for certain things and analog for the rest to clean it up. E.G. click some push buttons to get your date and laps.
The odd months problems doesn't apply to Casio watches. I remember being amazed in the 90' when I tried to set the date in a Casio watch and discovering I couldn't set the day of the week. I realized then the day of the week is adjusted automatically because the Casio watches had (even then - back in time) a complete calendar inside.
You raise perhaps some good points about legibility, but you probably know that casio have tons of models from ultra simplistic and classic to sophisticated models with sensors and multiple screens.
Attached a picture with a simple model (legible ?) screen with titanium body, solar power, radio sync and also the digital screen you mentioned it should have. It is also very thin.
I wanted to buy also this model but I feel the (even if small) digital screen doesn't go so well with the elegant look and classic analog dials. And I also grew tired of the mixed look - with the analog dials and digital display.
I also think you are probably Omega biased and probably equal things could be said against the Omega watches.
The opinions about looks are subjective but what's not subjective are Casio research about watches field. They had a number of firsts, or clear improvements in this field. I mentioned before the touch screen watches in the 80' which not only they were a first, but also had a simple and elegant look, they were small and thin, had a metal body, huge screen (especially for 1984) and water proof. They didn't look dorky and were not black plastic. For me at least in 1984 they were like something from the future.
Their new analog watches also have some improvements which frankly I expected them for quite a few years. Computerized motors pointer movements. I mean if I want to set the clock back a few hours (perhaps I had to change the battery, or my watch stopped) why should I turn the pointers clockwise which is the longest road ? When the shortest way is backwards ? Casio can do that and not only that, the pointers can move separately for the shortest road.
Not to mention invisible features like radio time sync, solar power without a visible solar energy screen, very long power time in the dark and others.
Also most people heard about the Casio watches reliability. There are stories about watches found on a bottom of a lake after years and they were still able to function and in good condition.
I shouldn't mention the price comparison because a good design is a good design, but still the Omega watch posted before cost like $ 3400 so they could in theory use 5 times more money on research but somehow I could swear Casio has a larger budget for that.
