The Breitling Watch Source Forums

Recently found a Breitling E79362 which was my father's a while back in pieces as he tried to replace the battery and everything is here except the two screws that hold the battery in ( must have been small and lost) is there any of these online or specific dimensions for them.
Sorry I'm new to watches but it's really nice and wanted to try and get it back up. Any links would be appreciated. I tried to have a look but couldn't find any, was probably looking in the wrong places. Thanks in advance.
