1950's Gubelin Automatic

Here we have a nicely aged Gubelin automatic, that appears to from the 50's. The steel case measures about 34mm in diameter, 18mm lug width. It's a solid, somewhat beefy case, with screw on back. Everything appears original, dial has a nice spotted patina, gold color hands and markers. I don't know the service history, but it keeps great time. Movement is very high quality, adjusted, 25 jewels. It's on a high quality gray suede leather strap. Seems like a very underrated brand. I'm asking $300 USD or best offer. Watch is located in Ohio. Please message me with questions and inquires.
Thanks,
Matt
