There are essentially two “Poor Man’s” two versions of Heuer Silverstone- one with the same charcoal dial as the Silverstone, and the other with a herringbone blue dial. While Heuer itself only sold the Charcoal version, the Sinn 105 was available in both colours. Lemania itself also sold its own branded version of the watch.

Some versions of these Silverstone’s come with a 5012 Lemania movement, which is a slower-beating version of the 5100 without the 24-hour register. It appears as though Heuer only used the 5100, which was modified to remove the 24-hour register (a little odd given that the 5012 already had this removed).

So, 5012 was only for poor man Silverstone branded Sinn and similar?
Interesting question.
