Historical significance

TAG Heuer Formula 1 37 mm Skeletonised Sapphire sits within TAG Heuer's Formula 1 line, introduced in 1990. It carries the house codes established since 1860 — sapphire crystal case case, skeletonised dial and automatic chronograph — and is one of the references collectors use to date the evolution of the collection.

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.
