Introduction/Identification of Omega Vintage Pocket Watch (15 Jewels)

Hello to all! I am a new member on here. Well, new in the sense that I am finally getting around to being active on here as I have been very busy with college. I am very new to watches, and extremely new to vintage watches. I would say that my interests of watches stems from my interests in existential philosophy and every film (EVER) I have watched about time travel (because there is always a watchmaker in said films haha). I am very much looking forward to being part of this community. I have recently received A Guide to Complicated Watches by F. Lecoultre as a gift and plan to work on my watch repairing skills/knowledge this summer! Two days ago I purchased a vintage omega via Ebay's Auction system. I am wondering if anyone could help me identify/provide useful info about the pocket watch? I intend to keep this as it is my first pocket watch and my second REAL watch...the first being a Seiko Presage that I purchased a few months ago. Thank you to everyone in advance!!

I am not sure how to add additional pictures without them being very small.... I have quite a few other pictures that show the movement and casebook lid... will try and post those in a bigger format so they are able to be better seen
