Hi:

http://www.standard-time.com/index2_en.php
4 x 12 meter 7-segment display where the segments are boards held in 
place by C-clamps.  One man can change one segment, but it takes 11 men 
and a couple of ladders to change two digits.  If fewer (wo)men were 
used the time to make a change would be longer than 1 minute and the 
clock not be good to a minute.  It looks like they started out using 4 
bolts at each joint with power tools and later changed to multiple 
C-clamps.  You can buy a DVD movie  that can be played on a PC where the 
video is synchronized to the PC time.  For more interesting On Line & 
Hardware Clocks see:
