well,
@Albert you may actually benefit from warranties with rep watches. some dealers offer it with or without papers. it is certain that these papers are only an aesthetic benefit, a perk if you want, to appear more attractive compared to the competition. those papers have no value in fact, but they only improve the shopping experience... in the era of consumption we live in, it's nice to benefit from an appealing packaging) I would definitely buy from dealers that offer this packaging than from those without it, even if it is the same watch))
at the same time, the price of the watch matters a lot in this equation. if the price difference for watches with and without papers is too big, I don't see any sense in overpaying, because they are just printed papers that, technically, you can throw in the trash)
