I am a new member who joined by the suggestions of members of watchuseek.com. I have this same watch as part of a collection of totally eclectic vintage watches from my in-laws that they saved from their parents as well. So some watches go back to 1800's.
RegaRding the Omega, it looks very similar to yours, but has Spanish for days of week and months. I believe was bought in Cuba in 40's. My in laws were there escaping from Belgium then. Or it was bought by gentleman who lived in Cuba who helped them enter the U.S. Legally at that time.
Since I am sending this from my iPad, I Will try to add image.
I am not a collector and my husband is not emotionally attached to the watch either. So I am researching the best options for resale. What are your recommendations.
Thanks,
Jltorcz
