It consists of three overlapping metal cubes made of steel and located on a concrete platform. In the middle and in two of its faces are the time planes and the astrological months. The clock works with two gnomes, one for the morning hours and another for the evening. In the hours near noon work the two gnomes projecting on different faces, identical shadows and the same hour. Both gnomes are the two lower vertices of the upper cube of the face, facing south. This watch was awarded the 3rd prize in 1999 in the 6th Edition of the Congress of Gnomónica celebrated in Italy. The designer of the sculpture is the artists Joan Olivares and Rafael Amorós.
