Other than its parts value (for the movement, assuming it is all correct), there is no real long-term value in these since they were not made by Patek, are not a design that Patek would ever consider & would never be authenticated by a Patek representative or collector. I hate to seem harsh, but these are monstrosities, nothing more. Patek made its name by producing finely-crafted works of horological art for men with style, not fads for the fashionable (the era of watches that can be seen from space ended some time ago, so it is difficult to even call them fashionable anymore).
Please do not waste your money on 1 of these. If you want a Patek, get a Patek. If the price is too steep, buy used or get a nice (simple) Patek rep. Or, if you must have a gargantuan watch, get 1 from a watch company that makes gargantuan watches.
