Abstract
Reloj perfeccionado, que siendo del tipo de los que presentan una ventana practicada en un punto de la esfera, por cuya ventana van apareciendo los números que definen ordinalmente los días de cada mes, se caracteriza esencialmente porque los primeros siete números figuran sobre un fondo de color verde, apareciendo los once siguientes sobre fondo rojo y los restantes hasta finalizar el mes otra vez en color verde, todo ello con objeto de vigilar los periodos fértiles de la mujer.
