Based on either an ETA calibre 2824-2 or Sellita calibre SW200-1, TAG Heuer Calibre 5 is one of the most well-known automatic watch movements in the industry. By looking at the jewel count engraved on the movement, you can tell which movement a Calibre 5 is based on. The ETA has 25 Jewels, while the Sellita contains 26. Many also feature a transparent sapphire case-back so you can observe the Calibre 5 at work.
Legibility and durability are the watchwords here. Waterproof, shockproof, and anti-magnetic, the Carrera is made to last. As for legibility, the clean dial and well-spaced markers make it easy for drivers to read the chronograph accurately at a glance.
The chronograph versions of today’s Carrera reissue have what’s sometimes known as a “tricompax” layout, with subdials set at 3, 6, and 9 o’clock. Many find this the most attractive style of chronograph design, because it inherently looks more balanced.
Heuer initially made stopwatches for racing drivers. The original Carrera watch, launched a good decade before sport chronograph watches became mainstream, was intended as a tool for the racing community – hence the archetypal motorsports aesthetic.
