One of the early Zenith watches to come out under the Dufour banner was the Retrotimer, a continuously running monopusher flyback version of the El Primero that features a little red hash mark at eight minutes on its lone sub-dial, as can be seen in the image below. When the watch came out, I remember hearing that the Retrotimer’s red mark was there for use in the kitchen. At first, I was told this by a fellow journalist, and I recall that some digging at the time turned up a press release that offered confirmation. I recall it saying something to the effect that a designer at Zenith had put it there because of his love of pasta, though I no longer have this press release.
