Designer
In-house design studio
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 Connected 37 mm Blue Carbon sits within TAG Heuer's Connected line, introduced in 1995. It carries the house codes established since 1860 — carbon tpt case, blue "grande tapisserie" dial and automatic chronograph — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
- Early production dials show a slightly different minute track, and collectors pay a premium for them.

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.
