to string in composite value objects

A simple question why do i need to have __toString in composite value objects such as GeoPoint ?

Option 1 :

class GeoPoint
{
    public function __construct(Latitude $lat, Longitude $long)
    {
        // do some work to check values and set them 
    }

    public static function fromString()
    {
        // parse object from string
    }

    public function __toString()
    {
        // to string representation
    }
}

Option 2 :

class GeoPoint
{
    public function __construct(Latitude $lat, Longitude $long)
    {
        // do some work to check values and set them 
    }

    public static function fromNative($lat, $long)
    {
        // parse object from $lat, $long pair
    }
}

wouldn't be a better to go with option 2 ?
