14K Gold Lord Elgin 1956

Here we have a beautiful condition Lord Elgin from 1956. American made, and solid 14k gold. I'm selling this for roughly it's scrap value! When I bought the watch, about a year ago, the seller claimed it was serviced. So it keeps great time. Dimensions are shown in the pictures below on the caliper. The lug width is 18mm. I have it on a gold plated Speidel. I'm asking $350. Ask me anything and check my references. Thanks for looking.
