Is it possible to know whether wear device is on wrist?

I want to know if it's possible to know whether wear device is on hand or not. I need to run a service who take pulse only when it's on hand, then if it's not, then it should stop service and start it again when it's on hand.

You can try using heart rate sensor

public class MainActivity extends WearableActivity implements SensorEventListener {

    private static final String TAG = "MainActivity";
    private TextView mTextViewHeart;
    SensorManager mSensorManager;
    Sensor mHeartRateSensor;
    SensorEventListener sensorEventListener;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mTextViewHeart = (TextView) findViewById(R.id.heart);
        mSensorManager = ((SensorManager) getSystemService(SENSOR_SERVICE));
        mHeartRateSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_HEART_RATE);
        mSensorManager.registerListener(this, mHeartRateSensor, SensorManager.SENSOR_DELAY_NORMAL);
        Log.i(TAG, "LISTENER REGISTERED.");
        mTextViewHeart.setText("Something here");


        mSensorManager.registerListener(sensorEventListener, mHeartRateSensor, mSensorManager.SENSOR_DELAY_FASTEST);
    }


    public void onResume(){
        super.onResume();
    }

    public void onAccuracyChanged(Sensor sensor, int accuracy) {
        Log.d(TAG, "onAccuracyChanged - accuracy: " + accuracy);
    }

    public void onSensorChanged(SensorEvent event) {
        if (event.sensor.getType() == Sensor.TYPE_HEART_RATE) {
            String msg = "" + (int)event.values[0];
            mTextViewHeart.setText(msg);
            Log.d(TAG, msg);
        }
        else
            Log.d(TAG, "Unknown sensor type");
    }

}

Some devices like the microsoft band 2 have a sensor specifically used to detect whether the device is worn or not. Depending on the project, you may consider developing for that device
