1970s Heuer Professional Diver (Ref. 844) Mk I "Monnin"

By the 1970s the Heuer brand had already amassed a rich pedigree as a watchmaker, though most of this success came from their innovations within the chronograph sector of watchmaking. And while these incredible watches, such as the Carrera and Autavia, were technically "water resistant", Heuer's first delve into the professional dive watch market wasn't until the ref. 844, known most notably for its French designer Gerald Monnin.

Uncharacteristically for Heuer, the ref. 844 was an immediate commercial success. This sudden demand spawned rapid changes within the reference, these variations or "Marks" all carry distinct characteristics that set them apart from one another with varying levels of value and collectibility attached. However, the very first version of the ref. 844, the Mark I, remains extremely collectible today. The ref. 844 Mk I along with the Mk II were made entirely in France, before production was moved to Switzerland for the later variants. The Mk I most notably employs ornate, cathedral-style hands with a dial featuring a military-inspired red 24hr scale and text that reads "METRES" and "PROFESSIONEL" instead of the "Meters" and "Professional" seen on the later models.
