What is a watch jewel (Jewel)?

Watch jewel , also known as Jewel, is an extremely important part of a watch’s movement. Watch jewels are usually made of precious stones, used to minimize wear and tear during the process. clock operation, invented in 1704 by Nicolas Fatio de Duillier, Pierre and Jacob Debaufre .

Bezels often appear on mechanical watches with many details in the movement and on some high-end Swiss or German pin watches, in order to reduce friction in parts, almost absent on copper models. ordinary battery pack.

Jewel means precious stone , used to refer to the origin of the material and to refer to the bezel as a valuable part, giving the watch a luxurious and classy look.

The word jewel in Chinese means glass leg, where the leg is the stand and the glass refers to transparency.

The function of the tripod

The bezel of a watch plays a very important role in a watch, because it directly affects the correct operation and durability of the watch. The bezel of the watch includes the following functions:

• Reduce friction between movements to increase watch accuracy

Usually, a watch has more than 200 different details. During operation, the parts of the watch are in constant motion, so friction is inevitable. Glass legs are often placed at the contact points of the parts to reduce the friction and wear of the parts, along with prolonging the life and durability of the internal components.

• Get the watch to work properly

The bezels are made of hard materials with low wear, so they can protect other parts of the watch, helping the parts work correctly, operate better and more stable.

• Improved shock resistance

In addition, the glass legs can increase the shock resistance between the components inside the watch, limiting damage.

• Enhancement of watch aesthetics

The higher the quality of the bezel, the more luxurious and classy the watch is. The delicate and eye-catching glass legs on the watch face will bring aesthetics to the user and enhance the use value of the watch.

• Increase the value of the watch

With high-quality, expensive materials such as diamonds or other precious stones also contribute to enhancing the value of the watch you are using.

Materials for making glasses

Previously, glass was usually made of precious stones or diamonds , but now, the jewels are made of many different materials, typically ruby or sapphire with high hardness and durability.

There are 4 common materials for processing glass legs: Sapphire, garnet, ruby and diamond. In addition to the common materials mentioned above, some manufacturers also use some wear-resistant alloys or metal-coated treated glass to make the jewels.

The common point of all the materials selected for the jewels is usually high hardness, difficult to wear and has the ability to reduce friction when they collide or come into contact with different parts inside the watch.

Dimensions of the tripod

Glass legs are usually very meticulously designed with a diameter of no more than 2mm and a thickness of about 5mm. However, depending on the watch line, the jewels have different designs or by order, the jewels will have their own sizes.

Position of the tripod

The jewel has the effect of reducing friction and limiting wear to the internal components of the watch, so the jewel is often placed in places where there is high contact between the components in the watch. However, there are still cases to beautify watches, jewels are placed in places with less friction to increase the aesthetics according to customer needs.

Popular types of glasses legs

Hole Jewels

It is a type of glass with a round, flat shape, with a hole drilled in the middle. This type is used to attach to the shafts of slewing gears with small rotational speeds, which do not require very high accuracy. Resistance to forces acting from directions perpendicular to the axis of rotation.

Cap Jewels without holes

Round, flat, in the middle without drilling holes, usually applied to the 2 ends of the rotating shaft with high requirements for error, high rotational speed, and greatly influenced by axial force.

Pallet Jewels

The brick shape is mounted on the points of impact, horizontal impact such as the two ends of the horse, sliding the lock trigger, the escapement (also known as the wheel of spikes).

Roller Jewels

Roller-shaped legs have a cylindrical shape, mounted only on the base of the pendulum so that the horse “rocks”, the point of impact is sliding (horizontally).

Shock Protection Jewels

There is no specific shape, located between the bezel and a certain part, preventing the jewel to be protected when the watch is subjected to strong shocks.

Related questions when choosing to buy watches with jewels

The more jewels, the more complicated the watch, right?

Many people think that watches with many jewels are complicated watches, but this is not the case for all watches. If it is a complicated watch, there are quite a few jewels because they have many interlocking active parts, so it is imperative to use multiple jewels to reduce friction.

However, a watch with many jewels is not necessarily a complicated watch because in order to increase the aesthetics of the watch, many manufacturers have increased the number of jewels into the watch to serve the needs of users.

How many new jewels is enough?

Surely, you are not sure how many jewels in a watch are suitable, both for aesthetics and maximum use of its capacity. The number of jewels to be installed depends on the construction and function of the watch. Here are some suggestions for the right number of jewels for each watch type:

• 4 jewels for pin watches with analog dials.
• 6 – 7 jewels suitable for battery watches, multi-function quartz watches.
• 17 jewels for wind-wound watches.
• 21 jewels for automatic winding watches.
• The 23 jewels are suitable for mechanical watches that have two drums (also called barrels) for power reserve.
• 25 – 27 jewels suitable for multi-function mechanical watches.
• Over 40 jewels are available for mechanical watches with complicated structure, for some other special watches there are up to 100 jewels.

Does the number of jewels tell the value of a watch?

Previously, the number of jewels did not make the value of the watch because with complicated watches, a lot of jewels were needed.

However, nowadays, quite a lot of people appreciate the aesthetics of the jewels, so the manufacturer tries to add more jewels to increase the price of the watch and increase the aesthetics.
