I saw these this morning. They did a whole bunch of colors. I don't understand why they won't do a version with the standard non-skeleton dial. Would make a much better rep.
I'm almost sure that it did not sell well, given that Zenith is not one of the popular brand, plus the fact that these were not well made.
Looking at this pic, the jewel color, as well as the fake escape well, already turned me off; As much as I wanted another zenith rep.
