*** ** * ** ***

Allows watch face creators to define the behavior of `SecondHand` elements, such
that the seconds increase in a smooth continuous motion.

Introduced in Wear OS 4.

## Syntax

```xml
<Sweep frequency="valid-value" />
```

## Attributes

The `Sweep` element has the following required attributes:

`frequency`

:   The frequency, in Hz, at which the hand is redrawn. Must be one of:
    2, 5, 10, 15,
    `SYNC_TO_DEVICE`

    If this value is set to `SYNC_TO_DEVICE`, the hand redraws as quickly as the
    device allows while keeping the sweeping motion smooth.
