Selecting image from image array

[mtn]

On a "site-settings" page, I have a "watches" image field that contains 5 images.  The first and last are easily echo-ed with"$a->first();" and "$a->last();", but I am having difficulty in creating the correct syntax to display images 2-4.  Any help would be appreciated.  Thank you!

Present code:

<?php $selectWatch = $pages->get("/site-settings/")->watches;
   $watchOne = $selectWatch->first();
    echo "<img src='{$watchOne->url}' alt='{$watchOne->description}' class='time'>";

?>

$first = $selectWatch->eq(0);
$second = $selectWatch->eq(1);
$third = $selectWatch->eq(2);
