Why are jewels used in watch movements?

Jewels or gemstones were introduced in watch movements to reduce friction at points of heaviest wear and tear. In order to reduce friction between two metal components that rub against one another, watchmakers use hard stones at the points of friction as they last a lot longer than metal.

How are jewels used in watches?

Watch jewels, sometimes known as jewel bearings, are tiny pieces of synthetic ruby or sapphire set into holes within a watch movement. These gems primarily help to reduce friction and provide a hard, smooth surface to allow metal components such as the wheel train to rotate freely.

Is more jewels in a watch better?

As a general rule, the greater the jewel count the better the watch. Jewels in the movement provide for smoother operation and much less wear over time.

Why do watch movements have rubies?

Essentially, the small rubies (also sometimes referred to as jewels) in mechanical movements are used as bearings for the pivots to reduce friction. Being strong and hard, they help to reduce friction and wear and tear amongst the mechanical parts. The more moving parts there are, the more rubies are used.

Are the jewels in watches worth anything?

The higher the jewel count of your old watch, the higher its value. A 17-jewel watch is considered to be fully jewelled. Historically, rubies were most used as the functional jewels in antique watches because they are hard and wear down slowly.

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.

What is the highest number of jewels in a watch?

The Watch with 242 Jewels In fact, the world’s most complicated watch has 242 jewels in its movement. It’s the Ref. 57260 from Vacheron Constantin, with a whopping 57 complications. Having 2,800 components, it only makes sense that its jewels also exceed in number.

Why is Rolex called oyster?

Today, the Rolex catalog is divided into two categories: Oyster and Cellini. Therefore, Oyster refers to any model that has a sealed watch case invented by the company in 1926.

What are jewels in a watch movement?

Do more jewels in a watch make it better?

It’s not the jewels themselves that make the watch better but the number of jewels in a watch can indicate how mechanically complicated or in some cases, how thin a watch is. Although the most jewels in a watch ever may be hard to track, oftentimes super-high complications watches have an unfathomable amount of jewels in the movement.

Why do some watches have more bearings than others?

If the watch has high-complications such as a perpetual calendar watch, a chronograph (a watch with a stopwatch function), or a tourbillon watch, it will require having more components to add these functions and will therefore use more bearings. You’ll also find that some ultra-thin watches use a higher number of jewels in their movements.
