grunt_futtock is my pseudonym from writing my book - click on link on home page for details. If you buy the book , it tells you how to solve the grunt_futtock ones, and how to solve the Symmetry bonus cache, but you don't have to buy the book to do the caches!
Google should help you solve the puzzle - if not, wind your watch forwards from 12.00 and see how many times it happens in twelve hours.
The secret here is to ignore the hint, the attributes and the profile. Try a left mouse click and drag over the text on the cache page to select it - something should appear telling you where to look.
Look there and you will find how to work out West and the hint.
If still stumped on West look at my non-puzzle caches and look for a series of caches, where you only need half the coordinates.
