For those among us with a slight inclination towards nostalgia, remember that it's full name is "4711 Echt Kölnisch Wasser" (4711 Real Cologne Water). Köln (Cologne in english) is a german city, and the home of the original cologne, which (probably) is this very fragrance. Made for over 200 years, and still in production. Like most of the very old concoctions, it is citrus based and was probably intended to be a refreshing balm more than a lasting fragrance, originally. The line of fine men that used this product is very very long.
Incidentally, all fragrances were unisex, back in the day. The notion that some fragrances were unsuitable for men was conceived by Napoleon, who would fine his officers if they wore anything he did not approve.
