Only problem, Ashley, is the cal 1002 is a faulty design and was quickly upgraded by the 1010 series (010, 011 and 012). Self lubrication, faulty automatic winding system and instantaneous date were all fixed in the base calibre 1010 . So the 1001 and 1002 while a nice idea and, with the exceptions above, not a bad piece of design, they are a dog to fix and are regarded as an horological failure, notwithstanding their presence in Ploprofs (but perhaps that could explain why we see so relatively few working Ploprofs around these days).
