Found some markings on the case edge. I haven't been able to find anything else that would tell if the case is gold or gold filled. Sent from my iPhone using Tapatalk
Looks a lot like mine.....on the inside https://omegaforums.net/threads/omega-pocket-watch-ca-1915.40966/ This should help
Thanks. That's what I was wondering. Pocketwatch 101 also said that only 5% of all pocket watches were solid gold so you're not likely to find one that isn't plated or gold filled (especialy for what I paid) http://www.pocketwatchrepair.com/how-to/case-material.php
A lovely piece of history, enhanced by some amazing photography too! Was that a microscope you used ;-) S
