Honestly I don't know a whole lot about Omega pocketwatches, it might be real, but the movement just doesn't look like one I've seen. Even if we do assume that it is real, Omega pocket watches from this era are VERY common and in extremely low demand, so much so that some Ukrainian ebay sellers are scrapping them and turning the movements into crappy wristwatches. The value of a real one is really very little.
