Rare Heuer 980.026 Black Coral Professional Diver from the 1980s with serial number 38309. The watch dates from the period in which there was only Heuer and no TAG-Heuer, so from before 1985. Models from before the merger between TAG and Heuer are very popular among collectors. Nearly everything that bears only the Heuer logo keeps rising in value. Heuer has never released an entirely black PVD jumbo oversized diver. This is the largest size they've ever had of this model. Complete watch in a rare matte black edition. From a private collection, first owner. The photos are part of the description.
