TAG Heuer Monaco Split-Seconds Chronograph in TH-Titanium: ultra-lightweight and visually unique

TAG Heuer presents a new edition of its Monaco Split-Seconds Chronograph, now crafted in TH-Titanium. Price of ref. CBW2185.FC8350 is CHF 145,000

TAG Heuer has unveiled a new version of its Monaco Split-Seconds Chronograph, first introduced in April 2024 (read about the two launch editions here).

This 2025 edition, reference CBW2185.FC8350, is distinguished by a visually striking new form of titanium. Named TH-Titanium, this texturised material is obtained through a proprietary thermal process developed entirely in-house by the TAG Heuer Institute, the brand’s R&D division based in La Chaux-de-Fonds.

Using this process, the metal is transformed at an atomic level to reveal its hidden structure. The result is a natural, irregular pattern that shifts with the light. The surface of each case is therefore entirely unique, shaped by the intrinsic composition of the metal rather than human intervention.

The titanium alloy used for TH-Titanium is known for its strength, corrosion resistance, and ability to retain energy. It is typically reserved for aerospace components, turbine blades, and high-performance automotive parts.

The 41 mm × 15.2 mm case is fitted with a bevelled, domed sapphire crystal that reveals the sapphire dial. Beneath it, the fine-brushed and polished black DLC-coated Grade 5 titanium bridges, along with the black opaline chronograph counters, create a striking contrast.

The rattrapante hand is finished in a vibrant lime green, a colour that also appears on the titanium rattrapante pusher and on the chronograph hour and minute counters at 9 o’clock and 3 o’clock respectively.

The caseback, entirely crafted from sapphire crystal, offers an unobstructed view of Calibre TH81-00, developed in partnership with Vaucher Manufacture Fleurier and also crafted in titanium.

Weighing only 30 grams, this movement is one of the lightest automatic chronograph calibres ever produced by TAG Heuer. It operates at a frequency of 5 Hz (36,000 vibrations per hour) and offers a power reserve of 65 hours with the chronograph off or 55 hours when it is running.

Its split-seconds function – also known as rattrapante – enables the measurement of two separate time intervals simultaneously, such as recording laps on a racetrack or timing multiple sporting events.

The openworked oscillating weight, shaped like the TAG Heuer shield and bearing the individual number of each timepiece, is hand-finished with fine brushing to highlight its contours. A hand-engraved chequered flag motif, a signature of the brand, adds a final layer of detail.

The light weight of the movement contributes to the watch’s overall mass: just 86 grams, including the hand-stitched black calfskin strap with a textile pattern and its titanium clasp.

The price of the new TAG Heuer Monaco Split-Seconds Chronograph in TH-Titanium, reference CBW2185.FC8350, is CHF 145,000. tagheuer.com
