Grammar I - 02.02
この / その / あの / どの+noun
  Kore, sore, are, and dare? can be modified by replacing the final re with no to specify an object.  

It is important to note that kono, sono, ano, and dono? cannot stand alone:  they must be followed by a noun.  

For example, if you know that the item in your hand is a watch (tokei) you can say:

この とけい  いくら です か。 How much is this watch?

kono tokei wa ikura desu ka?

 
  As opposed to:
これ  いくら です か。  How much is this?
kore wa ikura desu ka.  
   
 

Similarly, if you're talking about a watch that is held by the person you are taking to, you can say:

その とけい は さんぜん えん です。  
sono tokei wa san-zen en desu.  
   
  And if the watch is far from both the speaker and the listener, you can say:
あの 時計 は 三千  五百 円 です。  
   
ano tokei wa san-zen go-hyaku en desu. If you already know that one of several watches is 3.500 yen, but do not know which, you can say:
どの とけい が さんぜん ごひゃく えん です か。

Which one (of the watches) is of the 3500 yen?

dono tokei wa san-zen go-hyaku en desu ka?  
 

Since dono is a question world (just like dore discussed in 02.01), we cannot use the particle wa with it; we must use ga.

   
  To summarize:

これ(は~)/ この noun (は~)

this - close to the person speaking

それ(は~)/ その noun (は~) that - close to the person listening
あれ(は~)/ あれ noun (は~) that over there - far from both people
どれ(が~)/ どの noun (が~) which? - unknown
