Does a cleaned dial detract from a collectors viewpoint?
Yep. And it's nearly impossible to accomplish without a very high risk of damaging the dial.

It certainly does if it changes the nature of the dial or removes any of the script.

You mention that the watchmaker cleaned your dial.
Do you know what they did to the dial?
Did it actually need any serious cleaning or just dusting?
(most of us instruct a watchmaker to clean the dial with an angel's breath)

You can't tell your dial has been cleaned other than the dial looks pristine - which isn't a bad thing.

With the scratches on the original crystal (which I have) it was difficult to see the true condition of the dial. Once he had it apart we could tell the dial needed nearly nothing done to it, so I would rate that as a light dusting or damp cleaning.

The old crystal and the replacement crystal both have the proper Omega logo in the center.

Like the crown - the old crystal has the contemporary 'narrow, flat-footed' logo in the centre and the new crystal has the broader 'happy-feet' logo in the centre.

However, like the crown, crystals are deemed consumables and no-one really minds if they have been changed -so long as they have been replaced with the correct parts.

So the crystal and the crown are acceptable, and the dial is wonderful (for a 57 year old watch). And while the case isn't pristine like new it is certainly not bad.

Any thoughts on the medallion caseback?

An Omega crystal is important because it's part of the 'waterproofing' system.
The crown is also - but whether or not the seal in the crown is up to snuff depends on the age of the replacement (10-sided crowns haven't been available new for quite a while now)

I think the medallion looks pretty good - nice sharp brickwork on the observatory and very decent stars.

Agreed. Overall, a nice example.

Yes, the crystal seal is in place now, it wasn't before, and the crown seal is likely just a wish. This watch does not ever go near water.

Don't let it go near humidity either. I've seen more than a few dials that were never subjected to water intrusion, but were nonethlesss badly compromised as a result of high humidity environments due to poor or nonexistent crown seals.

Apparently, I handed my watchmaker extra crowns, he used the best choice, and returned the extras.

The one on the right is the contemporary crown.
Edit
For clarity - contemporaneous to the watch.
