This is an elegant 40mm automatic watch Swiss made by Oris. Model number 7504. This watch is in excellent condition, functioning perfectly and keeping time well.

The bracelet is in excellent condition with some normal wear appropriate for age. I don't have any extra links, but it fits my 6.75-inch wrist, loosely enough to fit one finger under the bracelet. Edit: 20mm lugs. The lume on the dial is still quite strong. See lume pics. Sapphire crystal, 30m water resistance. Powered by a 25-jewel Swiss automatic movement made by Eta. I'm not sure of the exact calibre. Includes date complication. The dial is almost black, but might be considered a very very dark grey. "Near-black", I would say. A lovely Swiss timepiece in a comfortable 40mm size. Excellent condition and function. Asking $505 USD OBO including shipping within North America.
