The number under the Omega sign on the movement is the calibre (looks like 285), the number on the movement (starts 1692...) is the movement serial number (around 1958-ish) and the number inside the case back 14714 is the case number. -61 is a year and SC means it's stainless steel. It's common for movements to be earlier than case numbers or sale dates. You can look the case number up in the vintage database: http://www.omegawatches.com/planet-omega/heritage/vintage-watches-database?ref=15274
