When you first get sucked into the world of watches, a couple of fundamental concepts await. First, you might learn to notice the difference between a seconds hand that ticks and one that smoothly sweeps.
But then, if you want to go deeper, you’ll need to understand more about the engine that powers the watch, which is called a movement โ and you’ll inevitably be faced with the terms mechanical and automatic.
This, however, is much more than a matter of terminology, as learning about their differences is one of the best ways to delve into how a watch movement actually works. It can be a point of confusion for watch newbies, but isn’t too hard to wrap your mind around. Here’s what you’ll want to know.
What is a “mechanical” watch?
A mechanical watch is powered by a spring. There are two primary systems for powering watches. One is via batteries (known as quartz) and the other is via a slowly unwinding spring โ that’s mechanical.
The tension of the spring unwinding in a controlled manner (rather than all at once) drives a series of toothed wheels which, in turn, rotate the hands around the dial.
