When diving into the world of watches, you’ll often hear the term “caliber”—but what exactly does it mean?
In simple terms, a caliber refers to the specific mechanical movement inside a watch that powers its functions. It’s the beating heart that controls how your watch keeps time, moves its hands, and powers any additional complications.
What Does Caliber Mean?
