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.
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.
Not necessarily. The jewels, often rubies, are intended to provide almost frictionless operation of moving parts. Their effectiveness depends on the quality of the jewels as well as the craftmanship with which the moving parts of the watch are manufactured and assembled.
The number of jewels in a pocket watch can usually be found by examining the watch's face or back cover, where it may be inscribed with the jewel count. Additionally, the movement of the watch can be inspected; often, the jewels are visible as small colored stones (typically synthetic rubies) set into the movement. Some manufacturers also indicate the jewel count on the watch’s documentation or packaging.
It is the model number of the movement. The Grade 384 was made from 1910 to about 1924, and had 17 jewels and was usually adjusted.
"17 rubis" refers to the number of jewels, specifically rubies, used in a mechanical watch movement. In horology, jewels are synthetic or natural stones used to reduce friction and wear between moving parts, improving the watch's accuracy and longevity. A movement with 17 rubies indicates a certain level of craftsmanship and complexity, often found in mid-range watches.

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.
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.

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.
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.
A very large number, if you include decorative jewels.
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.
The value of a 1910 Waltham Watch Co. 8-day, 15 jewels, adjusted watch can vary widely based on its condition, rarity, and market demand. Generally, such watches can range from $100 to $500, with well-preserved or rare models fetching higher prices. To get a more accurate valuation, it's advisable to consult with a watch expert or appraiser.
