The Royal Navy (UK) also had one called the "Admiralty Fire Control 
Clock" they where also used by the Royal Canadian Navy and likely the 
Royal Australian Navy as well.  The WWII fire control center for the 
land based harbour defences here in Halifax had one or two as well.  
They took several people to operate with each person inputting their 
assigned parameter.  For a time in his RCN career my father-in-law's 
action station was the "wind" on the fire control clock.
