You need to do a query of all of the posts where this field is used and then loop through all of the posts to collect a list of the values that are actually used. The only place that information is stored is in the _postmeta table related to each post.

For example:

global $post;
$cities = array();
$args = array(
  'post_type' => 'page',
  'posts_per_page' => -1
)
$query = new WP_Query($args);
if ($query->have_posts()) {
  while ($query->have_posts()) {
    $query->the_post();
    $city= get_field('city-field-name');
    if (!in_array($cities)) {
      $cities[] = $city;
    }
  }
}
