What is a ‘jewel’, and how does the number of jewels affect watch quality?

In all watches,especially the mechanical watches,such as Rolex replica,Porsche Design replica,Richard Mille replica,Zenith replica,Hublot replica,Ferrari replica watches the power must be transmitted from the main energy source (eg mainspring) all the way to the hands.This power transmission takes place through many rotating parts.In a mechanical wristwatch, whenever there is a rotating component, there is friction.This friction reduces the watches accuracy and takes away valuable energy the watch needs to keep running.

To minimize friction, watches are fitted with synthetic rubies on most gear pivots,such as Breitling replica,U-Boat replica,Bell&Ross replica,Patek Philippe replica and Omega replicas.The ruby is lab created, is generally round, and has a small hole in it for one end of the gear to fit in. The gears itself rotates in these rubies.The rubies contain a small drop of lubrication to further minimize friction.

To simply transfer energy from the mainspring to the hands, about 17 jewels are needed.Many high quality watches use 17 jewels.There is a common misconception that more jewels is better.This is not true. More jewels only means there are more rotating parts and the movement is more complex.For instance, a chronograph complication adds more rotating parts. The basic Poljot 3133 mechanical chronograph movement is 23 jewels; the same movement with a moonphase indicator is 25 jewels.
