Michael Stockton certainly coined a nickname that stuck with "Rising Sun," but the genesis of that nickname is bizarre:
"We gave the Omega Speedmaster Rising Sun its nickname due to its hue proximity to the Japanese flag. Sure, in this case, white is replaced with grayish silver and red with more of a burgundy, but we think it aligns perfectly well with the flag of the country that is hosting the Games in 2020. "
The above rationale is reasonable, if one ignores entirely the overarching history of why this watch is the color "red" in the first place: the 5 Tokyo 2020 watches represent the
colors of the Olympic Rings, which Olympic colors themselves represent the different continents: "The Olympic symbol expresses the activity of the Olympic Movement and represents the union of the five continents and the meeting of athletes from throughout the world at the Olympic Games.” (Olympic Charter, Rule 8)"
The red Olympic ring represents the Americas, while the yellow Olympic ring represents Asia/Japan:
So, there is a degree of both historical and geographic oddity in proposing a nickname of "Rising Sun" for an Olympic tribute watch specifically intended to represent the Americas within the suit of Olympic colors, and from a series commemorating an Olympics to be hosted by a country within the yellow continent.
Perhaps, though, this is more the fault of the European Olympic designers of the 1910's who decided to quite awkwardly indicate Asia as yellow (yikes!), Africa as black (watch out!), the Americas as red (jeez!), and Europe as blue-blood... I mean
blue.
May as well include a photo of the Tokyo 2020 that
actually represents Japan in the Olympic rings:
