Anyone know why rolex use the '28' in their SD date shots?

[jameshe]

Hi guys, as the title suggests, is there any trivia behind this, or is it simply because it was deemed to 'look good' in the date window on the sea dweller product shots? (see my sig as an example, and many more pics on the Internet - I am on my iPhone at the mo so unable to post them)

is the number 28 used on any other models? If not, is there any pattern/relevance behind it?

Has the number 28 always been used on the sea dweller shots going back to it's launch?

I am intrigued to discover why, if any of you guys know, and if not, perhaps I had ought to be sectioned under the WIS act!!
