Historical significance
TAG Heuer Aquaracer 42 mm Silvered Grade sits within TAG Heuer's Aquaracer line, introduced in 2004. It carries the house codes established since 1860 — grade 5 titanium case, silvered opaline dial and spring drive — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- Early production dials show a slightly different minute track, and collectors pay a premium for them.
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
- 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.
