Vintage TAG Heur Professional men's watch, relative purchased overseas long ago. Just replaced battery, and it works! Don't know if it's the real thing, but it sure looks the part. Time/date adjustment seems limited, needs cleaning, and not sure how well it keeps time over the long run, so selling for cheap.
*Update* - watch does not appear to keep good time with a new battery. It was sitting in a drawer for years, so it will likely need service and/or cleaning inside the case. Good as an accessory, but not as an accurate timepiece. Make offer.
