Aker音叉晶体CTS3-32.768-9-20-R为何开创新的精度标准?在这一突破之前，所有的钟表都是纯机械运转的。通过安装石英晶体和使石英振荡的相应能量源，首次引入了电子元件。这确实奏效了:新款石英表的走时比纯机械手表精确得多。
但是石英晶体实际上实现了什么功能呢？简而言之，高质量石英晶体确保手表“知道”一秒持续多长时间。这是通过产生恰好1赫兹的频率来实现的。赫兹是频率的常用测量单位。它表示周期信号中每秒重复过程的次数；在这种情况下，秒针在表盘上前进一个位置。
32，768赫兹音叉无源晶体的唯一标准频率来自哪里？要理解这一点，你必须知道石英晶体的频率取决于它的形状和大小。一个自然频率只有1赫兹的石英会如此之大，它更适合“大本钟”钟楼，而不是手表。显然，从生产和使用的角度来看，这是相当不切实际的，所以有一个特殊的技巧。Aker公司匠心缔造石英晶体编码CTS3-32.768-9-20-R，Crystal，无源晶振，频率为0.032768MHz，频率公差为±20ppm (Tol) ，负载电容为9pF，脚位为2-Pin，SMD，T/R.
