Dating a swiss army watch
Some American watch brands did not use a consistent series of serial numbers, but most of the big manufacturers did.

Be sure to use the table that is specific to YOUR brand of watch when looking up your serial number.
You must use the serial number from the MOVEMENT of the watch... You usually have to take the back off the watch case to see the movement serial number which may appear anywhere on the watch movement. Be sure to use the serial number on the watch movement (the mechanism).
The knives do not always follow the regular evolution on the tools, so here you need to use the evolution as best you can and the tang stamps the emblems.
You need to have attention if the knife is a regular economy knife or if it got advertising (promotion).
