like Su Song's clock and the elephant clock warrent their own article. I think that this is no differnt. However, it should at least be mentioned in the Modern water clock designs section. 

 I included a link on the Hydrochronometer page for the source info, but that article really needs to be expanded. 

 == England section and other recent edits == 
 Topics that are loosely related to the Wiki article do not belong. I suggest recent editors refer to Wikipedia's topics: 
 Wikipedia:Relevance of content and Wikipedia:Policies and guidelines.  —Preceding unsigned comment added by   •    

 == too many references == 

 This page needs to have far fewer references or way more text to be brought in line with wikipedia's guidelines. If you don't know about them, reply here and I'll find them for you.   

  
 How many refs are allowed in accordance to Wiki's guidelines? I'd love to add more content, as much more is needed. The problem is time. Even going through and selectively removing some refs could be laborious. I'm probably the most qualified to do so, since most of the content and refs came from me. Guidelines would be helpful. It's too bad though, because these are really good - it's like a dream for anyone doing research on the subject; half the work is done.   —Preceding comment was added at   

 == Babylon or Babylonia? == 

 Are the early water clocks from Babylonia, or just the city of Babylon? The article says Babylon (the capital of Babylonia), but I find it hard to believe that the technology wouldn't have spread.
