I've always loved the Zenith Rainbow series, and finally managed to snag one of the rare yellow dialed chronograph versions, or as my wife calls it, "my Steelers watch." Powered by the venerable EP400, it is one of 470 made in the late 90s/early 00s.

Turns out that it was purchased only in April of last year from AD in Jamaica and still had some of the blue plastic on the sides. The white "gunk" (for lack of a better word) on the bezel came from the pillow, which had seriously deteriorated, and will hopefully come out once I clean it.
