Its got 40+ years on it, If you plan to wear it a lot, I would consider an service. The 6119 is a work horse, but 1970's lubrication has long since dried out and you mosdef have some things rubbing that shouldn't be.
BTW- I have been a seiko fanboi for 25 years and have seen only 1 of your exact reference. As you can see in the images below from their 1968-1971 JDM catalogues, there are a lot that are close, but not exactly on point.
This could have been from 68-71, but not a JDM. Or it could be from 72 or 73 (which I don't have JDM catalogues for)
What is the serial number? XYxxxx X=year, Y=month, xxxx is unique to watch.
So 93xxxx in your case would be March, 1969.
Either way, dope piece. And it was your mom's, which makes it even cooler. Your mom is cooler than me.
