Not only would the watch with the most "flaws" be hard to detect under the circumstances we all experience in ordinary life, I believe the photos establish that a watch can have lots of little "flaws" and still be quite attractive.
Yes, when we look at the photos to detect any minute differences those of us with trained eyes can see them simply because we know what to look for. BUT look at it the other way. Instead of looking at those watches to see the minor "flaws" look at them to see the similarities. The watches are 5% different visually; but also are 95% the same visually. Notice how the blue color is the same, notice how the sheen on the dial is the same, notice how the SS is the same, notice how the gold is the same, notice how all three present the same striking presence, notice how the hands are all the same (none use ss hands), notice how the Rolex crown is all the same, notice how the word Rolex under the crown is all the same, etc. Basically, all the things an ordinary person will notice when looking at those watches are going to create the same impression. Unless a person knows to look for misaligned m's on the dial, they won't notice that "flaw," same with solid midlinks, gold on the sides of the midlinks, etc. Even the lowest priced rep in this sampling looks very good. That is amazing: a $125 watch which looks so, so identical to a $10,000 watch. Simply amazing, I am impressed with the $125 watch for what it is able to do at that price. Some people call watch no. 1 "cheap." I think that is unfair to the watch and doesn't respect it for all the things it does get right. It is better to call it inexpensive (a fact) and containing the most flaws of these three (a fact) but the watch should be respected for the 95% of things it gets right and does so for a very low price.
I still have all three of these watches and am not embarrassed to wear any of them. I get compliments on whichever of them I happen wear; no one ever says "look at those misaligned m's on the dial!" or "I can see some silver on the sides of the midlinks" or "the 4 on the bezel is not the correct font." To ordinary people in the real world these three watches are identical. They see the 95% positive image; only we seem to obsess over the 5% "flaws." And that is fine, it is educational, we want to be able to select the "best." But we don't have to unnecessarily run down the least expensive watch in the process.
