Luminescent, self-powered marine buoy that is constituted from a wrap-around and watertight casing of material and shapes suitable to be as stable as possible, as far as buoyancy is concerned, it is essentially characterized in that a chassis or casing is provided internally to said casing internal, whose base presents a small cylindrical and hollow extension in which a shaft mounted on suitable bearings, such that the outer end of said shaft involves open and torn holes in which play a few tetons that emerge horizontally from a pivoting and vertical axis which in turn is subject to one of the ends of an arm whose opposite end carries a counterweight, with the particularity that said arm and counterweight are freely located inside the envelope and with freedom of rotation without reaching to touch the inner wall of such envelope, having provided that the other end of the mentioned axis firstly, it is fixed and geared to a cylindrical crown disposed internally of the internal housing or frame and whose crown comprises two lateral gears of smaller diameter, on which both shafts are mounted and supported by free rotation by means of bearings to a bushing fixed to turn to the internal casing or beater itself, so that on the ends of the two aforementioned axes have been provided toothed wheels with a retention mechanism in one or the other direction and further characterized because on the periphery of the cylindrical drum is mounted a gear that is combined with another of smaller diameter provided at the end of an axis that emerges to the outside of the frame or internal casing and whose axis involves a pulley that transmits the movement to a dynamo, through the corresponding transmission belt.
