When I was little I always told him I wanted his watch. He has now passed recently and I received that watch I always wanted. I just want to see if any of you can tell me what year or era it's from because I have no idea and how much these sold retail in that era. Im very curious.
The various parts brought together sometime in the 20th century. Most are not kin. Quite the heirloom, wear it in good remembrance.
The boys are joking around, I'm afraid the watch is not historically significant to anyone but you. Memories and provenance are priceless! Get the repair costs estimated and then decide the value of your memories. Tell all the experts to screw themselves and enjoy the warmth in your heart, the warmth in reliving your families' history!
Your original question was one of identification. Did you read and understand the link I showed you? That's the only way we will be able to tell you about your watch. As to your other question, the crystal is broken and should be replaced. This should be done as part of a service. Find a competent local watchmaker and get it cleaned/lubricated/adjusted and then enjoy it for what it is.
TLDR It might be worst case a fake. Best case made up from parts. We need to see the movement. At a minimum the caseback is not an Omega part
