26 Νοε 2020 · Watch jewels, jewel bearings, or simply jewels can be found within a watch’s movement. They’re described as tiny synthetic ruby or sapphire pieces set into the holes of the movement. We all know mechanical watches do not require batteries to function.
Jewels in a watch are tiny translucent pink or purple stones, also called rubies. Combined with proper amounts of lubricant, watch jewels serve as bearings to reduce friction in areas of the movement that would otherwise be metal to metal. Having jewels improves the accuracy and longevity of a watch.
What are jewels in watch movements? The jewel in movements is actually bearings. The jewel bearing is a plain bearing in which a metal spindle turns in a jewel-lined pivot hole.
Watchmakers use jewels or precious stones inside of mechanical watches to reduce friction between the surfaces of moving metal parts. The wheel train bearings and the escapement in a watch can get worn quickly, especially without lubrication, so the jewels help keep them running smoothly and accurately.
19 Φεβ 2024 · Watch jewels are synthetic jewels, often sapphires or rubies, placed in different parts of the movement. Their main job is to reduce friction between pieces that rub against each other. Keep in mind that this is a very different thing than precious stones that are placed for decoration.
Jewels are used to reduce friction, increase accuracy, and improve the durability of your watch. Typically, luxury and higher-grade watches use ruby jewelled movements to prolong the life of the watch.
A watch with 17 jewels is often called a fully jeweled watch. This means that it uses jewel (usually ruby) bearings in the mechanical movement from the balance wheel all the way to the center wheel pivot.
