I have had this used but original Heuer dial for several years now hoping to find the rest of the parts to build one of these. I finally gave up because the case is all but impossible to find. The dial is for a Landeron cal 189 and I have only seen one other with the date at 12 (most are at 9 with no sub second). So over the last couple of weeks I put this one together from a bunch of spare parts. It turned out rather nice even if not original. Don't worry, I am NOT going to sell it - its just for my own use and besides, I refuse to pay over $1000 for a Landeron based chrono when I can buy a much better vintage Heuer for the same money.
