Thank you to everyone who posted responses. I want to especially thank Mr. Coop and Mr. Darom for taking time to share their thoughts on this subject.
I wish I could post a response to every question and every comment here, but that would take all week I'm afraid of sending this discussion in a more negative direction by going tit-for-tat so to speak.
Each of you has certainly brought many things to light that I have not considered before.
I think the most remarkable thing that I've learned from this thread is that this niche in photography focuses on creating a single image that will be used for multiple purposes. Knifemaker's portfolio. Collector's inspection. Printed media showcase. Online distribution. This all-in-one approach is pretty fascinating, and I'm sure that has a lot to do with the distinctive style in this area.
I agree that my original rolex photo was not particularly outstanding, but I'm certain that the selling point of that particular model was the "window" into the gold mechanations behind the watch face. Putting the black watch against the black background was a cool way to emphasize that detail, in my opinion. I do suspect that this is a third party's attempt at making a wallpaper and that Rolex can't be blamed for the typo or the odd composition.
And Mr. Coop: My name is Kent Bell. I am an artist, graphic designer, art director and part-time metalsmith living and working in Venice, CA. If you would like my address, email, phone number or any other information, please feel free to contact me.
