QUESTION: What i don't understand is how to find out the size of the watch i keep seeing size 12 and such and i don't understand jewel movement, i see everywhere else that it states on the mechanism itself but mine does not, so how do i know what the movement is if it does not state it.
Answer Ms. Rebecca,
Jewels were used to cut down on the wear caused by metal rubbing on metal. It is used when a pivot will fit inside a hole. The hole would fit a jewel that is shaped like a donut. When the pivot is set into the jewel, there will be far less wear than if the metal was rubbing on metal.
Because there is less rubbing, it is cutting down on friction. As a result, the watch is more accurate. The more jewels, the more accurate the watch should be.
Size, that is an interesting story, I believe that it was Mr.Dennison who made the scale for American watches. To determine the size of an American watch, one uses a Lancashire gauge. To give you an idea of how it works, a size 10 is 1 15/30 inches. A size 11 is 1 16/30. Size 12 is 1 17/30 inches, and so on, right up to size 20, 1 25/30 inches.
The Swiss have a completely different measurement system.
