Quartz crystals are used in a wide range of electronic applications where timing is a fundamental parameter. Owing to the high ‘Q’ factor of quartz, these crystals can deliver accurate and relatively stable timing signals to a wide range of low-frequency applications. One of the most common crystals used is the 32.768 kHz watch crystal, known for its superior performance in time-keeping and clock applications typically in internal microprocessors in laptops, mobile or cell phones, GPS devices, and virtually any device requiring accurate timekeeping, including real-time clocks (RTC), test and measurement equipment and battery powered applications.

石英晶体被广泛应用于各种需要定时作为基本参数的电子应用中。由于石英具有极高的“Q”值，这些晶体能够向广泛的低频应用领域提供精确且相对稳定的定时信号。最常用的晶体之一便是32.768 kHz的钟表晶体，它因在计时和时钟应用方面的卓越表现而著称，这些应用通常见于笔记本电脑、移动设备或手机中的内部微处理器、GPS 装置，以及几乎所有需要精确计时功能的设备，包括实时时钟（RTC）、测试与测量设备以及电池供电型应用。
