Can you Overwind an automatic watch?
Unlike the handwound watch, you can’t overwind your automatic, but don’t overdo it — the winding mechanism in an automatic is typically less robust than that in a handwound watch and thus more vulnerable to breaking with careless or excessive use. Let the watch wind itself.
What do gems do in watches?
Stones or jewels are used in watches to prevent or reduce friction between the surfaces of moving metal parts within a watch. When metal rubs against metal in the absence of lubrication, the moving parts like pivots and bearings in a watch can get worn quickly, which can lead to the watch breaking down.
What does 25 jewels mean in a watch?
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.
What is 21 jewels in watches?
As all watches have many moving parts, jewels were inserted to lessen the wear and tear on the bearings and other pivot points. The jewels basically make the watch movement last longer. …
Are jewels in watches 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.
Why are there jewels in a watch?
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.
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.
Does adding diamonds to a watch lower the value?
When Adding Diamonds to a Luxury Watch Can Decrease Its Value. Many people believe that adding diamonds or gemstones to a watch will invariably increase its value. In some cases, this is correct since the intrinsic value of the added materials will augment the value of the watch itself.
Why do they use rubies in watches?
Jewels (rubies) are used as bearings to reduce friction at critical points, to improve the accuracy and durability of watches. One of the hardest materials after diamond, ruby (a corundum) do not wear – almost. As a consequence, jewels can be made very smooth which allow low friction with metal pivots.
How many jewels are in a Rolex?
31 jewelsThe calibre 3135 uses 31 jewels, and has a diameter of 28.5mm, with a height of 6mm. Due to the design of the mainspring, Rolex is able to squeeze a 48-hour power reserve into the watch, which is slightly longer than the power reserves of many other, similarly-sized movements.
What is the highest number of jewels in a watch?
17Most jeweled watches have around 17 jewels that are used in several areas: Balance Wheel. One impulse jewel can be found in the assembly where the escapement level hits it.
How can you tell how many jewels a watch has?
Thus, removal of the dial is usually required to determine the accurate count unless the plate is marked as “17 Jewels.” Generally, if the center hole is jeweled and the movement is not marked with jewel count, it is likely 16-jewels. 17-Jewel movements are usually marked with the jewel count.
What is 15 jewels in a watch?
15 Jewels: Higher quality watches also have jewels for the bearings of the pallet staff and the pivots of the train wheels. There are two jewels for the pallet staff, and two each for the third, fourth and escape wheel pivots, another eight jewels on top of the seven in the balance and escapement making 15 in total.

What are the jewels in a watch made of?
The jewels are typically made from the mineral corundum, usually either synthetic sapphire or synthetic ruby. Jewel bearings are used in precision instruments where low friction, long life, and dimensional accuracy are important. Their largest use is in mechanical watches.
Are more jewels in a watch better?
Not necessarily. A typical hand-wind movement today will have only 17 jewels as a full complement. Some really high-grade or ultra-thin movements will add a few extra jewels to further protect against any wear, but even these top out at 21-23 jewels.
