It has changed some materials and changed some colours, but essentially the rectangular design with the side button and the Digital Crown has been retained. This however, could change slightly in the next generations .
According to a report by Fast Company, Apple is going to replace the current buttons with new generation ones that work slightly differently. You will still have the side button and the Digital Crown, but they will no longer be mechanical buttons. What does this mean? It means that they will no longer have a travel when pressed, they will no longer be traditional buttons. When pressed, they will reproduce a vibration that will give us the sensation that we are making a tour over them. The Digital Crown will maintain its rotation.
It seems that Apple is considering adapting a functionality that has worked so well on the iPhone , the haptic home button. Since the iPhone 7 and iPhone 7 Plus, the iPhone with a Home button has no travel on the button, but is a touch button that gives the sensation of pressing it and having travel. That’s because of the Taptic Engine, Apple’s built-in haptic engine for improved vibration.
Switching to haptic buttons isn’t just a whim. It brings benefits to the user and especially to Apple’s engineers in creating the device. Because haptic buttons don’t require a single path, Apple can use the space inside the button for other components , such as more battery power or simply to reduce the size of the clock.
Moreover, while the Apple Watch is already waterproof up to 50 meters from the Apple Watch Series 2, these new buttons can further improve that resistance . As they are haptic, there is no separation between the button and the rest of the watch, but they are one piece. This avoids any leakage of liquids or particles inside.
