Date and Timer Labels
Date and timer labels display real-time values on Apple Watch.
Date label. Displays the current date, the current time, or a combination of both. You can configure a date label to use a variety of formats, calendars, and time zones. After configuration, a date label updates its value without further input from your app. For developer guidance, see WKInterfaceDate.
Timer label. Displays a precise countdown or count-up timer. You can configure a timer label to display its count value in a variety of formats. After configuration, a timer label counts down or up without further input from your app. For developer guidance, see WKInterfaceTimer.
Consider using date and timer labels in complications. When you use the system-provided date and timer labels, watchOS automatically adjusts the presentation of the label content to fit the available space. For developer guidance, see CLKRelativeDateTextProvider.
