The watch combines high-tech materials with cutting-edge regulating technology. You get Swiss precision engineering in a package built for extreme conditions.

The Heart: Calibre TH20-61 Movement

The TH-Carbonspring oscillator represents TAG Heuer's latest breakthrough. This ultra-light component resists magnetic fields and shock better than traditional materials.

Design That Commands Attention

The Dial

The forged carbon dial features a spiral-engraved pattern. This design takes inspiration from the TH-Carbonspring geometry inside the movement.

At 6 o'clock, you'll find the flying tourbillon. This mesmerizing complication rotates continuously, showcasing the movement's precision.

The dial includes:

• Minimalist subdials for clean readability
• Facetted black gold hands

• Grey markings for tonal finish
• Water resistance for daily wear

The pushers and crown also use forged carbon. This creates a cohesive, stealth-like appearance throughout the watch.

Why Carbon Fiber Matters

Carbon fiber brings three key advantages to watchmaking:

Weight Reduction Your wrist won't feel fatigued during extended wear. The material weighs significantly less than steel or gold.

Durability Forged carbon resists scratches, impacts, and daily wear better than traditional materials. You can wear this watch during sports activities without concern.

Modern Aesthetics The black carbon finish creates a contemporary, technical appearance. This appeals to collectors who prefer modern design over classical styling.

Performance Under Pressure

TAG Heuer designed this watch for extreme conditions. Whether you're racing, diving, or traveling, the timepiece maintains accuracy.

Shock resistance handles impacts from sports activities. The movement continues running accurately even after significant jolts.

Tachymeter Function Explained

The carbon tachymeter bezel measures speed over distance. Here's how it works:

Start the chronograph when you begin measuring. Stop it after traveling exactly one kilometer or one mile. The chronograph hand points to your average speed on the tachymeter scale.

This feature proves useful for motorsports enthusiasts and pilots who need quick speed calculations.

Limited Production Details
