The Utility, Simple and Colour watch faces each include a large second hand, which you may find helpful for conveniently timing periods of less than one minute.
Under watchOS 2 and later, Apple Watch can remain awake for:
- Up to around 6 seconds, when waking the watch by raising your wrist;
- Up to 15 seconds on being tapped (the default setting), or;
- Up to 70 seconds on being tapped.
For your choice of the longer time periods to apply, interact with your watch by tapping the display or pressing the Digital Crown. For example:
- Wake your watch by tapping on it, or;
- Wake your watch by pressing the Digital Crown once, or;
- Tap on the display when the watch is already awake, or;
- Press the Digital Crown when the watch is already awake (for example, if it is set to Resume Last Activity on wrist raise, you may need to press the Digital Crown to return to the watch face).
To choose between 15 and 70 second time periods:
On your iPhone, in the Watch app, go to: My Watch > General > Wake Screen - under On Tap, select the setting for 15 or 70 seconds.
Note that, if your wrist is lowered during that time, your watch will still return to sleep.
