An exceptional design statement from the peak of the 1980s Swiss tool watch era, this TAG Heuer 3000 Professional reference 934.213 is presented in its sought-after midsize footprint. This luxury quartz diver features a distinct 36 mm matte stainless steel case (excluding the crown), a thin 9.0 mm profile, and a 40.4 mm lug-to-lug length. The defining feature of the 3000 series is its unique, angular 7-sided heptagonal unidirectional rotating bezel with a gold-plated finish, matching the fluted screw-down crown. Beneath the flat mineral crystal sits an immaculate slate-gray matte dial, complete with round luminous plots, classic Mercedes hands, and a rapid date-change calendar mechanism at 3 o'clock. Crucially, this lot includes the factory-original, integrated two-tone stainless steel and gold-plated bracelet with an 18 mm lug width, showcasing the early Heuer shield emblem stamped onto the fold-over safety clasp—a rare component that is frequently missing from this reference line. Powered by a high-grade Swiss quartz movement, all functions are fully operational with a fresh battery installed. Condition Report The timepiece is in good, honest vintage condition for its age. The blasted steel case lines remain nicely structured, while the gold-plated surfaces on the bezel edges and central bracelet rows show typical cosmetic thinning and micro-abrasions from decades of respectful wear, adding a beautiful authentic patina. The mineral crystal is clear, and the folding clasp clicks shut firmly. The bracelet shows moderate vintage play and fits a maximum wrist size of approximately 18.0 cm. This lot is sold as the watch with its original bracelet only, with no reserve price.
