Heuer 1000 Professional Diver Automatic Ref. 844/3 – 1983 Monnin Case Legend in Superb Condition

We are delighted to offer this highly collectible 1983 Heuer 1000 Professional Diver, reference 844/3, an iconic evolution of the famed Monnin design that marks one of the most significant milestones in Heuer’s dive watch history. With its robust 42mm stainless steel case, automatic Swiss movement, and tool-watch DNA, this model embodies the transition from outsourced production to in-house Swiss excellence.

Historical Significance & Design

Heuer’s entry into the dive watch world began with the Monnin Ref. 844, a response to increasing demand during the 1970s for rugged, purpose-built underwater timepieces. Initially produced by French case maker Georges Monnin, these early references gained quick popularity and were prominently featured in the 1979 Heuer catalogue. As demand surged, Heuer brought production back to Switzerland, marking a turning point in the lineage.

The reference 844/3 offered here belongs to the second wave of Monnin models—fully Swiss Made and powered by the dependable ETA 2872 automatic movement. This model represents a bridge between the original French-sourced Monnins and the later 1000 Series under the TAG Heuer branding, making it a historically rich and transitional piece in Heuer’s dive watch legacy.
