Designer
Jack Heuer
The reference was drawn by the manufacture's internal design office, where case, dial and movement architects work alongside the watchmakers rather than as an outside commission.
Historical significance
TAG Heuer Monaco 36 mm Blue 18k sits within TAG Heuer's Monaco line, introduced in 1978. It carries the house codes established since 1860 — 18k yellow gold case, blue "grande tapisserie" dial and high-beat automatic — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.

Brand history
TAG Heuer has spent more than 166 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Carrera, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Edouard Heuer established TAG Heuer in 1860, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every TAG Heuer calibre produced today.
