Concord Bumper Automatic 1950's

Here we have a stainless steel Concord bumper automatic, I'm guessing from around 1950, not a watch you see often. It reminds me of the bumper Omega's from the same period, for a fraction of the price, and every bit as good. The watch appears all original, minus the age appropriate strap I put on. The case measures 34mm in diameter, 18mm lug width, screw on case back. Movement keeps great time, although I do not know the service history. The numerals are a reflective silver. I'm asking just $175, as I'm thinning out the collection and hoping for a quick sale. Ask me anything, and check my references, they're all good. Thanks for looking.
