There are many categories of jewel movement, for example, 17 jewels, 21 jewels, or 25 jewels. The actual meaning of these numbers is just a representation on the number of rubies used within the mens watches
Tiny synthetic gem crystals are set between many of the gears, in order to reduce friction. These gems resist temperature better than metal, and hold lubricant much longer.
Originally, the natural rubies were used before a major switch to industrial-grade or synthetic rubies for cost efficiency reason. There are two important points about rubies that make them suitable to be used as bearings.
Firstly they are extremely hard (it can be as hard as diamonds) to withstand high frequency of abrasion and wearing. Secondly, its smooth surface is perfect for the various steel components in the watch to operate on with much reduced friction.
With the high load and high speed motions within watches, the two advantages of ruby clearly outweigh any possibility of using steel bushings.
You can actually hear the jewel movement working. The ticking noise of mechanical watches are actually made by two rubies banging into the steel teeth of the escape wheel. You should make sure to have your watch serviced every five years, as the toughness of the rubies can erode the steel if not properly looked after.

Was there a Louis Watch Company that made a watch called 25 Jewels?
It is the Louis Watch Co. from the 1950s that was located on Fifth Ave in NY
Is it more expensive for a watch that is 25 jewel or 17 jewel?
Generally, a watch with more jewels, such as 25 jewels compared to 17 jewels, may be more expensive due to the increased complexity and craftsmanship involved in its movement. The additional jewels help reduce friction and wear, potentially improving the watch's accuracy and longevity. However, the overall price also depends on other factors like brand, materials, and features, so it's not solely determined by the number of jewels.
What does 14J mean in a Nixon watch?
In a Nixon watch, "14J" refers to the presence of 14 jewels in the movement. Jewels, typically made of synthetic ruby, are used in watch movements to reduce friction and wear, enhancing the watch's accuracy and longevity. The number of jewels can indicate the complexity and quality of the watch's movement, with more jewels generally suggesting a more sophisticated mechanism.
What does a watch with 18 jewels mean?
A watch with 18 jewels refers to the number of synthetic rubies or sapphires used in its movement to reduce friction and wear on the moving parts. Jewels are strategically placed in areas of the movement where there is the most friction, such as the escapement and gears, to enhance the watch's accuracy and longevity. The presence of 18 jewels typically indicates a quality mechanical watch, as more jewels can signify a more complex movement. However, the number of jewels alone does not determine a watch's overall quality.
What does 15 jewels in a watch mean?
In a watch, "15 jewels" refers to the number of synthetic rubies or other gemstones used as bearings in the movement. These jewels reduce friction between moving parts, enhancing accuracy and durability while minimizing wear. The number of jewels can indicate the quality of the watch; typically, more jewels suggest a more complex movement. However, the actual number needed for optimal performance can vary depending on the design.
What are jewels made of?
watch jewl are made from cut up jewels
What are jewels when talking about a watch?
Jewels are typically attached around the frame of the watch, or ocassionally around the band. Such jewels can be cubic zirconia or actual gens such as diamons and opals.
What does 4 jewels on a watch mean?
In watchmaking, the term "4 jewels" refers to the use of four synthetic jewels, typically made of rubies or sapphires, in the watch movement. These jewels serve as bearings for the moving parts, reducing friction and wear, which helps improve accuracy and longevity. While more jewels generally indicate a more complex and higher-quality movement, 4 jewels is often found in simpler or less expensive timepieces.
What is the maximum jewels a watch can have?
A very large number, if you include decorative jewels.
What is nineteen jewels on a watch?
The numbers of jewels that are referred to in watch movements all depends on the make and manufacture of the watch. Certain companies like Waltham used extra jewels in the mechanisms of their watches, and 19 was referred to as a 19 jewel movement.
What does 12 jewels on a wrist watch mean?
In a watch, the jewels refer to bearings for the shafts of the various moving parts as well as the escapement. Jewels, as opposed to plain bushings, tend to be harder and lower friction and thus wear far less and also tend to make the watch run better. The 7 jewels is the minimum for a functional jeweled movement, this includes 2 jewels for the balance wheel pivots, and balance wheel pivot caps, one roller jewel and 2 pallet jewels (the roller and pallets are part of the escapement). Higher jewel counts have more of the wheels (gears) in jeweled bearings.
What is a number of jewels?
In the context of watches, "jewels" refer to small synthetic rubies or sapphires used in the movement to reduce friction and wear on moving parts, thus improving accuracy and longevity. The number of jewels in a watch typically ranges from 17 to 25, with higher counts often indicating a more complex mechanism. While more jewels can enhance performance, other factors like craftsmanship and design also play significant roles in a watch's quality.
