Reasonable price for 1950 Automatic

[SMH1965]

Greetings all - I recieved this watch in my father's belonging. I have some idea that it was gifted to him for some work he did back in the '60s. I am looking to sell it and would like to understand the rough value. Based on the serial number and references I found, I think it is from 1950 or 1951. Thanks for any help you can provide.

I suggest you search SOLD listings on eBay.
