Does "reading a clock face " necessarily mean "reading out what time the clock points?" For example, by reading the clock face, the blink man knows it is 3 o'clock afternoon.
Context:
One blind person was even able to identify and find objects placed on a table in front of him, as well as walking around a room independently and approaching people, reading a clock face and differentiating seven shades of grey. The device, which has been developed by the company Retinal Implant AG together with the Institute for Ophthalmic Research at the University of Tuebingen, represents an unprecedented advance in electronic visual prostheses and could eventually revolutionise the lives of up 200,000 people worldwide who suffer from blindness as a result of retinitis pigmentosa, a degenerative eye disease.

Ah yes the German guy with a chip in his retina.
"To read a clock face" you have to be able to do two things: 1. See the clock face and its hands 2. Interpret the positions of the hands - know how to "tell the time".
@oristarA,
There are two types of clocks commonly used. One is a digital clock, which simply renders the time in ciphers, such as "12:03." The other is an analog clock, which renders the time by analogy, with the "hour hand" and the "minute hand" pointing to positions on the face of the clock. That is what is meant by reading a clock face.
