The reproduction elephant clock in the Ibn Battuta Mall, Dubai.
The elephant clock in a manuscript by Al-Jazari (1206 AD) from The Book of Knowledge of Ingenious Mechanical Devices. [1]

The timing mechanism is based on a water-filled bucket hidden inside the elephant. In the bucket is a deep bowl floating in the water, but with a small hole in the centre. The bowl takes half an hour to fill through this hole. In the process of sinking, the bowl pulls a string attached to a see-saw mechanism in the tower on top of the elephant. This releases a ball that drops into the mouth of a serpent, causing the serpent to tip forward. At the same time, a system of strings causes a figure in the tower to raise either the left or right hand and the mahout (elephant driver at the front) to hit a drum. This indicates a half or full hour. Next the snake tips back again and the sunken bowl is raised out of the water. The cycle then repeats. [2] Serpent is a word of Latin origin (serpens, serpentis) which is ultimately derived from the Sanskrit term serp, that is normally substituted for snake in a specifically mythic or religious context, in order to distinguish such creatures from the field of biology. ... A mahout is a person who drives an elephant. ...
