Trying to figure out if this a genunie omega vintage, seller claiming this from the very early 1900s it has very unique dome shaped top. how can i find out, and what should this be worth ?
Caliber R17,8 was introduced int 1939 so it cant be any earlier than that. Can't say for sure without a clear photo of the movement. Refinished dial, very polished case, small size, poor condition movement, maybe worth $150 US if you really like it.
