"TAG Heuer Monaco Flyback Chronograph TH-Carbon Spring"
This flyback chronograph utilizes the TH-Carbon Spring, a new technology developed over the course of approximately 10 years. The TH-Carbon Spring is used as the balance spring material, and not only does it provide excellent magnetic and shock resistance, but its light weight reduces inertia, contributing to improved timekeeping performance. While new technology is prone to problems, the company has demonstrated its confidence in its technology by verifying its reliability through thousands of hours of repeated testing and offering a five-year warranty.
Automatic movement (Cal. TH20-60). Power reserve: approximately 80 hours. Carbon fiber case (diameter 39mm, thickness 14.1mm). Water resistant to 100m. Limited to 50 pieces worldwide. Price: 6,132,000 yen (tax included).
Based on the TAG Heuer Monaco, this timepiece features a design that emphasizes the TH-Carbon spring. The case and dial are made of forged carbon, which offers the material's unique lightness and robustness, as well as a marbled pattern.
Equipped with a flyback chronograph movement, it can be instantly reset and restarted while the chronograph is running. It has a 30-minute counter at 3 o'clock, a small second at 6 o'clock, and a 12-hour counter at 9 o'clock.
"TAG Heuer Carrera Tourbillon Chronograph Extreme Sports TH-Carbon Spring"
Another new model using the TH-Carbon Spring is the TAG Heuer Carrera Tourbillon Chronograph Extreme Sports TH-Carbon Spring. Like the TAG Heuer Monaco Flyback Chronograph TH-Carbon Spring, this innovative material is used in the balance spring to improve magnetic resistance, shock resistance, and timekeeping performance.
Automatic movement (Cal. TH20-61). Power reserve: approximately 65 hours. Carbon fiber case (diameter 44mm, thickness 15.4mm). Water resistant to 100m. Limited to 50 pieces worldwide. Price: 6,132,000 yen (tax included).
Most of the exterior, including the case, dial, push buttons, and crown, is made of forged carbon fiber. Its lightweight construction makes it easy to handle even in racing situations. The case back is made of grade 2 titanium with a black DLC coating. The black rubber strap is fitted with a grade 2 titanium folding buckle.
This model is equipped with the Cal. TH20-61 automatic tourbillon movement. An aperture at the 6 o'clock position on the dial allows viewers to enjoy the dynamic movement of the tourbillon carriage. The dial features a concentric pattern that radiates like a ripple from the aperture. The chronograph function allows for measurement of up to 12 hours.
"Tag Heuer Carrera Astronomer"
The TAG Heuer Carrera Astronomer is a uniquely designed moon phase watch. It comes in three variations, two of which are limited to 500 pieces each.
Automatic (Cal. 7). Power reserve: approximately 50 hours. Stainless steel case (diameter 39mm, thickness 12.16mm). Water resistant to 100m. Price: 671,000 yen (tax included).

The moon phase on this model differs from the typical one that uses a small fan-shaped window. It features a rotating disc at the 6 o'clock position, with a hand drawn on the disc pointing to an illustration of the lunar phase. Visually, the moon phase disc is easy to understand and corresponds to the 29.5-day lunar cycle. The moon phase disc is designed to rotate at 1:00 AM every day. An observatory motif is engraved in the center of the case back, creating a design that evokes the mystique of space.
The regular model features a silver dial with a black moon phase and a stainless steel bracelet.
One of the two limited edition models features a silver dial with an 18K rose gold-plated flange, and is mounted on a bracelet with 18K rose gold central links. The other model comes on a leather strap and features luminous indices.
