This is a Breitling Chronomat automatic chronograph in stainless steel and 18k yellow gold. It features the classic rider-tab bezel, champagne dial with three subdials, date window, and screw-down pushers.

The watch is running and keeps time well. Please note that one of the gold rider tabs on the bezel (front left) is missing, which is reflected in the price. (hence the low price) Otherwise, it presents nicely with the rest of the bezel tabs intact and strong overall appearance.
