De Ville 165.008, with the super-slim 711 movement. The latter almost always had lower-case "automatic" on the dial so are easy to spot.
@Boojumhunter excellent handle, I love Carroll's 'The hunting of the snark':
In the midst of the word he was trying to say,
In the midst of his laughter and glee,
He had softly and suddenly vanished away–-
For the Snark was a Boojum, you see.
