Do Quartz Watches Have Jewels? A Detailed Answer – WatchRanker

If you’ve ever had a watch serviced or browsed the specifications of a fine timepiece, you’ve likely encountered the term “jewels.” In the world of mechanical watches, a high jewel count is often a mark of quality and craftsmanship, touted right on the dial. But when you look at a modern quartz watch, you rarely see this feature advertised. This leads many to wonder: do quartz watches have jewels at all? The answer is more nuanced than a simple yes or no, and it all comes down to the fundamental differences in how these watches operate. We’re here to provide a clear and detailed explanation to settle the question: Do Quartz Watches Have Jewels? A Detailed Answer – WatchRanker.

The presence of jewels in a watch movement is one of the most misunderstood aspects of horology. Many assume that these tiny, synthetic rubies are there for decoration or to signify luxury. In reality, their purpose is intensely practical. To grasp why a quartz movement is built differently, we first need to understand what these jewels actually do and why they were so revolutionary for mechanical watchmaking long before the first quartz tick was ever heard.

What Are Watch Jewels and What Is Their Real Purpose?

Watch jewels, almost always synthetic rubies, are not placed in a movement for their beauty or monetary value. They are hard, polished bearings that serve a critical engineering function: to reduce friction. In a mechanical watch, dozens of tiny metal gears and axles (called pivots) are constantly spinning against each other. Without protection, this metal-on-metal contact would cause rapid wear, generate damaging debris, and make the watch highly inaccurate and short-lived.

By setting these high-stress pivot points inside a synthetic ruby jewel—an incredibly hard and smooth material—friction is dramatically reduced. This minimizes wear, improves the longevity of the movement, and allows for more consistent timekeeping. The jewels also help with lubrication, as oil is better retained on their smooth, non-porous surface. So, in a mechanical watch, more jewels typically mean more pivot points are being protected, which is a sign of a more complex and durable movement.

The Heart of the Matter: Mechanical vs. Quartz Movements

This is where the core of our question lies. A mechanical movement is a intricate world of tiny, interconnected spinning parts, all powered by a unwinding spring. It’s a purely kinetic system, and friction is its greatest enemy. A quartz movement, on the other hand, is a hybrid of mechanics and electronics. The power comes from a battery sending an electrical current through a tiny quartz crystal.

This crystal vibrates at an incredibly precise frequency when electrified. A microchip then translates these vibrations into a single, steady electrical pulse per second. This pulse drives a small stepper motor, which in turn moves the gear train that turns the hands on the dial. While a quartz movement does have a gear train, it is vastly simpler and operates under completely different conditions. The gears are not under constant torque from a mainspring; they only move in tiny, precise increments once per second. This results in far less stress and friction on the components.

So, Do Quartz Watches Have Jewels? A Detailed Answer – WatchRanker

Yes, some quartz watches do have jewels, but they are far fewer in number and their role is different. You will not find a quartz watch with 17, 25, or 40 jewels like in a mechanical watch. Instead, if jewels are present, they are typically used in the one or two places where friction is still a genuine concern.

The most common location for a jewel in a quartz movement is in the rotor of the stepper motor. This is the part that converts the electrical pulse into a physical turn. The pivots of this rotor move very quickly and can benefit from the reduced friction of a jeweled bearing to ensure efficiency and long-term reliability. Beyond that, you might find a jewel or two in the critical pivot points of the motion works (the gears that drive the hour and minute hands), but often, modern engineering and lubricants make them unnecessary. In many budget-friendly quartz movements, manufacturers use advanced polymers and composites that are self-lubricating and durable enough to function for years without needing a jewel.

Why You Don’t See “Jewels” Advertised on a Quartz Watch

If you’re looking at a quartz watch specification sheet, the jewel count is rarely, if ever, a highlighted feature. There’s a simple reason for this: it’s not a primary selling point. The accuracy of a quartz watch comes from the stability of the quartz crystal and the precision of the integrated circuit, not from a low-friction gear train. The marketing focus is rightly placed on features like battery life, accuracy ratings, water resistance, and material quality.

Furthermore, a high jewel count in a mechanical watch signifies complexity and hand-finishing. In a quartz watch, a jewel count is simply a practical, functional choice made by the engineers for a specific component. It doesn’t carry the same horological prestige. A quartz watch from a brand like Citizen or Seiko may have a very well-made and reliable movement with a few jewels, but its value is derived from its overall performance and technology, not this one component.

Key Takeaways on Jewels in Your Timepiece

To summarize, the role of jewels in watchmaking is all about context. In a mechanical watch, they are a fundamental necessity for reducing friction in a complex, kinetic system. In a quartz watch, they are an optional engineering solution used sparingly in specific areas where it makes technical sense. The presence of jewels in a quartz movement is a sign of thoughtful construction, but their absence does not indicate a poor-quality watch. Modern materials science has provided excellent alternatives that perform the same function just as well for the less demanding environment inside a quartz movement.

When choosing a watch, let this knowledge guide you. For a mechanical watch, a higher jewel count is generally a positive indicator of quality. For a quartz watch, look instead to the reputation of the brand, the quality of the case and crystal, and the stated technical features. The question of jewels is an interesting footnote in its construction, not the main event.
