Playfully dubbed “Pepsi,” the now-iconic red-and-blue watch bezel style dates back all the way to the release of the Rolex GMT-Master in the mid-1950s. Since then, it has become an inextricable part of horological culture and couture.
After having graced the aforementioned legendary Rolex travel watch, it has made an appearance on Tissots, Heuers (pre- and post-TAG), Japanese Seikos and even humble Timexes (and just about everything in between).
Now, Timex has returned to that signature styling on what could be one of the best combinations of good looks and budget-friendliness. The Timex Harborside Coast Multifunction is a remarkably affordable yet eye-catching watch.

GM-Tea, anyone?
So the story goes, the original Pepsi bezel was commissioned by Pan Am, the now-defunct airline, from Rolex. Pan Am wanted a watch that would allow its pilots to reliably track multiple time zones — hence, the GMT functionality.
Furthermore, the color scheme served a specific purpose. The split on the dial is said to represent daylight hours (in red) and nighttime hours (in blue), making them easier to discern.
