Why have jewels in a watch

These battery-powered watches primarily operate using an electrical circuit featuring a quartz crystal; however, there remains some gearing to enable hand rotation.

Jewels are placed within these gear bearings, to smooth their rotation and preserve accuracy and durability over time. A jewelled quartz movement can have between 5 and 10 jewels, depending on the manufacturer and number of complications chronograph watches, for example, will feature more jewels due to the faster moving parts. Many budget quartz movements feature no jewels, including those powering digital watches which require no hands. Unlike with mechanical movements, jewels are not essential to make a quartz watch accurate.

Unfortunately, as modern watch jewels are man-made gems, they are not as valuable as their naturally occurring counterparts present in other jewellery, such as expensive necklaces and bracelets. Typically, these synthetic jewels are available to purchase for as low as a couple of pence per unit.

Therefore, contrary to popular belief, jewels are not the reason that some watches cost a substantial amount of money. Despite what watchmakers and retailers may have you believe, the jewel count does not inherently mean the watch is better quality than other wristwatches.

Often the number of jewels is simply correlated with the number of complications the watch has. The more friction that builds up, the slower the gears would move. Over time, your piece would display time that is way behind. By no means do they need jewels to function. You can find some great quartz pieces without them inside. Why is this? There are a very few inside, and they are not as intricate as in their mechanical counterparts.

The gears in cheaper quartz pieces are usually made from plastic. They have steel in them. These jewels are usually synthetic rubies more on this below that have a very specific sized hole. They work hand-in-hand with their holed counterparts. Cap jewels are placed alongside the pivot attached to a hole jewel, preventing it from moving sideways. They usually come with some kind of shock resistance, protecting the gear if the watch is ever is dropped.

Ever seen a pallet fork before? This type of jewel looks like one. Instead, it works in pairs with itself. Remember how we said pallet jewels transfer impulses? As you know, real jewels were used back in the day. The jewels used these days are their synthetic counterparts. Just like its synthetic counterpart, real emeralds are used to adorn watches to this day.

As you can imagine, these watches cost as much as a car. There was nothing functional about the jewel. It was there for decorative — some would say deceptive — purposes only. However, the idea had taken hold and with no patent in place the idea of using jewels in watch movements became pervasive.

Watchmaking and clockmaking in England progressed using jewels as the holding element within the movement, enabling Harrison among others to create clocks that held a hitherto unmatched degree of accuracy. By hoodwinking Parliament, the Company had done De Duillier out of a fortune but without the actions of the Company the use of jewels would have been greatly restricted.

It was the Court and Master of the Worshipful Company of Clockmakers that included the likes of Thomas Tompion and Daniel Quare that turned clock and watch manufacture into a well defined and necessary part of the daily life of all. Gone were the days when a clock, and certainly a pocket watch, were an expensive and talking point object for the noble and well-to-do household.

Watches and clocks were now a necessary part of timekeeping for daily life, for the navigation of ships across the seas, and to understand the nature and rhythms of the heavens above.

It would be another lifetime — , to be precise — before the idea would be taken up by Ferdinand Berthoud, the first continental watchmaker to adopt jewelled movements. From there, it spread to the whole Swiss watch industry and beyond, and — with the major change being the introduction of synthetic sapphires — remains a key element of movement construction to this day.

The pivots and jewel bearings of the balance wheel are especially fragile and would often get damaged under impact. They were a major cause of repair. With anti-shock systems, the jewels are mounted on springs allowing them to shift in their setting, in order to absorb radial or axial shocks. Incabloc, Kif or Etachoc are the more common shock protection systems for Swiss movements.

The jewels are shaped so that the capillary action of the oil causes it to be drawn towards the gear axles instead of spreading all over. Very complicated watches can have over 40 functional jewels. In conclusion, jewels ensure that a watch can function for longer periods until it requires servicing, and that the damage to high wear-and-tear points is greatly reduced. It is worth noting that some brands have brought back the use of chatons — a difficult technique where small brass or gold settings are used to fit the jewel into the movement plate — and in some watches the setting of jewels is almost an art form.

Watch collectors are less interested in jewels today as they are now easy to include and are produced from synthetic materials. View all. Carl F. Your email address will not be published.
