Watch jewels, sometimes known as jewel bearings, are tiny pieces of synthetic ruby or sapphire set into holes within a watch movement. … The predictable friction of these jewels aids accuracy and their durability helps to increase the life of the bearings.
What do the number of jewels in a watch mean?
Jewels are the small red or clear circles that are sometimes visible the faces of various watch movements. … Original watchmakers used mined precious rubies, but nowadays the actual crystals used in watch movements are mainly synthetic. The jewel count refers to the number of pivots with inset rubies – or “jewels”!
What does 25 jewels in a watch mean?
Automatic watches are fully jeweled with 17 jewel bearings. Olyn has 25 for smooth self-winding. Virtually every mechanical watch contains a stash of jewels secreted within the case. These gemstones serve as bearings for the metal pivots of the movement’s gears, wheels, and pinions.
How many jewels are in a Rolex?
To give you an idea of what we mean, a modern chronograph like the Rolex Daytona has 44 jewels; however there are behemoths like the IWC Il Destriero Scafusia which has a flying minutes tourbillon and boasts 76 jewels.
Are the jewels in a watch worth anything?
The higher the jewel count of your old watch, the higher it’s value. A 17 jewel watch is considered to be fully-jewelled. Historically, rubies were most commonly used as the functional jewels in antique watches due to the fact that they are hard and wear down slowly.
What is the highest number of jewels in a watch?

How many jewels in a watch is good?
How Many Jewels in a Good Watch? Approximately 17 jewels are used in basic mechanical watches, though modern watches with self-winding (automatic) capabilities will typically house 25-27 jewels.
Are more jewels in a watch better?
The more complicated a watch gets, the more jewels it requires for more lubrication and less friction when moving. Complicated watches don’t only fall on high-end or luxury watch brands such as Patek Philippe, Rolex, or Omega. A lot of them can also be found in mid-tier and even entry-level watches.
What is 21 jewels in a watch?
What does 21 jewels mean in a watch? Similar to a 17-jewel watch that has a fully jeweled movement, but also has a few extra capstones added which are used to reduce positional errors. These extra stones are often found in higher-quality watches.
Why Are Rolex So Expensive?
The in-house development costs that go into the craftsmanship and design of their watches are said to be very high. It costs a lot to have the movement designs developed and assembled. And besides that, the materials that make up the construction of Rolex watches aren’t cheap either.
Is Rolex real gold?
Rolex exclusively uses 18 ct gold, a princely alloy composed of 750‰ (thousandths) of pure gold, plus exactly the right mixture of elements including silver and copper necessary to produce the different types of 18 ct gold: yellow, white and Everose, Rolex’s exclusive pink gold alloy.

Why are jewels in watches?
Jewels serve two purposes in a watch. First, reduced friction can increase accuracy. Friction in the wheel train bearings and the escapement causes slight variations in the impulses applied to the balance wheel, causing variations in the rate of timekeeping. … Second, they can increase the life of the bearings.
