Pocket Watch Number Of Jewels

Help identify a pocket watch?
I recently bought a pocket watch (my first) at a flea market and I can not find info about it. On the front it says "Boulevard" and less "Swiss" under the second hand. 17 jewels. The hood back is engraved on a train. The opening to the rear, it is written, saying "MA Mead & Co. 470 years. Inside back cover has a serial number as well. Can you give me some information about it?
Most of the old pocket watches, the movement is by a company and the case by another. You can go to a jeweler in the days and select the type of move you want and what kind of cases, depending the amount you want to pay. So when someone says a pocket watch is a Gruen, Elgin, Hamilton, etc., he means that he has this movement. It may even not say outside, or face and where appropriate carry the name of a jeweler, not a movement manufacturer. There are books that have pictures of all movements. You might find one at the library, or if you can find someone who collects pocket watches or corrections of old. Where is probably not important unless it is particularly pleasant, perhaps solid gold, or has lots of engraving or working hands on it. I never heard of A. Mead & Co., but I guess this is probably the company that made the case.
