Reading distance for Analog Clocks



Reading distances are distances between the clock and an observer, derived from practical experiments. 
For analog clocks, black DIN bar markings and black bar-type hands-on white clock 
faces (in accordance with DIN 41 091) were used.  
All distances are given as aids to orientation only and are without obligation.
