About Watch Complications

A watch complication is any function that exists in addition to telling time (displaying hours, minutes and seconds) on a timepiece. These watch complications enable special functions that are performed and displayed on the watch to enhance or simplify your life.

The more complications that exist in a watch make it more difficult to design and create because a number of additional elements must be built into the standard movement. Several complications are available in timepieces today, from simple date displays to complex functions such as a tourbillon or repeater. These watches are highly sought after because of an appreciation for the genius innovation in design, as well as the complexity, precision and skill required to create such a timepiece.

Recent advances in technology have spawned watches with GPS capabilities and that can sync with your Bluetooth phone, but when you remove the back of the case, you aren’t amazed by its battery or computer chip. This is the difference with complicated timepieces. When you view the movement of a complicated watch through its case-back, you’ll see technical innovation and precise engineering. The combination of several hundred tiny gears, jewels and springs enables the timepiece to complete incredible functions; functions that are assembled by hand and not completed by a computer chip.

An API for complications

Third parties have been able to make Android Wear watch faces for some time now, but the kind of information they can display is heavily dependent on the watch face itself—even with lots of options, it might be hard to find one that looks good and gives you the glance-able information you want.

Wear 2.0 introduces a full-fledged API for complications, those little snippets of extra information on dumb watches (or on the Apple Watch, for that matter) that show you things like the current date or moon phases. The Complications API lets app developers pass raw data to watch faces, which can format and style the data however they want to make it look good next to the rest of the watch face. Tapping on individual complications can take you into the full watch app for more information.

These complications should obviate the need for purpose-built weather or fitness-related watch faces, among others. All we need are apps and watch faces that use the API.
