Pocket watch stamped empress a.w.c.co case made in Canada with duracy made in US 7 jewels what year of manufacture and worth?

Hello - What do you mean by "with duracy made in US"? I have a watch with an Empress case and the movement is Lonville, a Swiss maker. I am guessing that the watch was made and sold sometime between 1900 and 1915. I recently bought a similar one for about $55. They are not really worth much unless they are in mint or Excellent condition -- the most you could get would be $300 or so, I believe. Anyway, I would be interested in buying yours for parts. Good luck!
