I definitely agree with you - lots of PP, ALS, AP, JLC etc automatics with beautifuly decorated rotors.
However, the recent trend of sapphire display backs has exposed us to a litany of boring rotors hiding the nicer mechanical bits underneath.
Why do we need to see this?

I do not want to offend anyone here, but frankly, to me, an automatic watch is something between a proper mechanical watch and an quartz watch, with disadvantages of both. I might be biased though, as I have never owned one.
- Automatic watches are unnecessarily thick. This is true mainly for dress watches.
- It is simpler - less parts to break.
- Winding a manual watch is a sort of a mystical experience.....
- It is obvious that a watch’s timekeeping depends on the degree to it is wound. .....
- For those of us who prefer display case backs, automatic watches should always be inferior, as the rotor obscures a significant part of the movement....
- Rotor adds to the watch’s weight. ....
- .........For me automatic watches are just a passing fashion without past and future.
Cheers.
It is obvious that a watch’s timekeeping depends on the degree to it is wound. The more wound is the mainspring, the slower the watch is (the differences are not huge in decent watches, but are always there). With manual watches wound every 24 hours, the average “winding degree” is exactly the same every day, which allows for much better consistency. Automatic watches are wound more or less depending on whether the watch is being worn, how it is being worn, whether a winder is applied and so on. It is then more difficult to achieve consistency, so special contraptions need to be applied such as coaxial escapement, to at least partly take care of this. Such solutions make the watch unnecessarily complicated and unnecessarily expensive. I think that if you compare similar hand wound and automatic movements, the former will always be more consistent. I am not a professional though, and would gladly hear some comments from people more qualified than myself.
Rotor adds to the watch’s weight. While I do not have anything against a reasonably heavy watch on my wrist, everything has its limits. Omega Speedmaster 125 weighs 185 grams. It is like having a full glass of water in your hand all the time - you can injure yourself. That’s a pity, as it is a beautiful watch and I would gladly have one, if it were manual. By the way there were instances in the past (no joke) of faultily designed self-winding mechanisms which, once the rotor achieved certain amplitude, caused serious wrist injury, but I assume that coming across such a watch nowadays is not very probable.
Why constrain yourself? 😀
Okay I'll comment - this is nonsense from a technical point of view. Automatic watches are typically near the top of wind the entire day while being worn, so not only are they more consistent in terms or torque delivery through the day, they are pretty much fully wound when you take it off at night. So your manually wound watch will be at 24 hours from fully wound when you wind it the next morning (spending the last 8 hours going from 16 to 24 hours after full wind, so the torque is dropping off), where the automatic watch will be going from 0 to 8 hours after full wind by the time you out it on the next day, and the torque will be higher. None of this has anything to do with co-axial escapements, etc.

Unless you provide some evidence of this, I'm going to call shenanigans...
If no winding mechanism is used at night wouldn't the mainspring be mostly relaxed by morning and introduce some slight barely measurable error?
Please do not call me that. I am 100% sure that I read about it on some watch forum within last year (the information contained there could be of course untrue). It referred to some watch (not Omega of course) that had double (multiple?) rotors that interacted in a somewhat unexpected way causing serious wrist damage. Unfortunately, I was just trying to locate that information and could not do it. Will continue searching. For now, I just need to live with the fact that the respect I have for you is not reciprocated due to my fault entirely. Lesson learned.
