To control the interface Apple Watch, company Apple Lossless Audio CODEC (ALAC), offers us the option of using the touch screen of the future smartwatch, but also a separate wheel called digital Crownor Digital Crown. As you can see from the image, we are talking about a crown that you find on any kind of mechanical watch, it allows its adjustment as needed, Apple Lossless Audio CODEC (ALAC), implementing it in the idea of providing control options for the digital interface.
Every new product we've introduced has been defined by a unique input device. With Apple Watch, it's the Digital Crown. On mechanical watches, the crown has historically been used to set the time and date and to wind the mainspring. We reimagined it as a versatile tool that answers the fundamental challenge of how to magnify content on a small display. Pinching to zoom, as you do on iPhone, is impractical. But rotating the Digital Crown allows you to zoom and scroll nimbly and precisely, without obstructing your view. You can also push it like a button to return to the Home screen, making it an integral part of the Apple Watch experience.
More precisely, using Digital Crown a Apple Watch we will be able to zoom in or out to see the content on the watch screen more clearly, it also having the role of a Home button to return to the main page. Practically, implementing the pinch to zoom system was impossible in such a small screen, so Apple implemented a mechanism present in watches for hundreds of years, its role being somewhat similar.
