The Tag Heuer Monaco V4 Phantom stands as one of the most innovative creations in modern watchmaking. First introduced in 2004 at Baselworld, the Monaco V4 redefined mechanical engineering with its belt-driven movement. In its latest form, the Monaco V4 Phantom pushes the boundaries even further by incorporating CMC carbon-based composite materials across the movement and case. This not only reduces weight but also provides a distinctive brushed-metal visual texture. Collectors admire its combination of futuristic engineering and the iconic Monaco silhouette, making it one of the most technically compelling Tag Heuer pieces ever produced.
Carbon Matrix Composite (CMC) Technology in the Monaco V4 Phantom
The signature feature of the Tag Heuer Monaco V4 Phantom lies in its use of CMC – Carbon Matrix Composite. This material is produced by aligning ultra-fine carbon fibers under high heat and pressure. The result is a lightweight surface that exhibits a brushed, hand-finished visual effect. For the first time in the V4 lineage, the bridge plates of the movement are entirely crafted from carbon fiber, contributing to the watch’s overall weight of just 98 grams — the lightest Monaco V4 ever made.

Lightweight Case with a Unique Carbon Pattern
The 41 mm square case features oriented-carbon micro-blasting, which ensures every single unit has a unique carbon-fiber pattern. No two Tag Heuer Monaco V4 Phantom watches look exactly the same. This process gives the case an almost architectural character, balancing precision with organic surface variation.
Advanced Engineering – The V4 Linear Winding System
Inside, the Monaco V4 Phantom continues to showcase the engineering that made the V4 collection famous. The movement incorporates:
- Seven CMC carbon bridge plates
- 268 total components
- Mainplate and gears coated in titanium-carbide
- Four barrels arranged in a V formation
- Patented linear-winding system driven by 0.07 mm micro-belts
- 42-hour power reserve

The belt-driven system remains one of the most unconventional mechanical solutions in Swiss watchmaking. Rather than relying on traditional pinions and gears, the V4 employs micro-belts similar to those used in motorsports — a fitting nod to the Monaco line’s automotive inspiration.
