Quick summary
- TAG Heuer has introduced the Monaco Evergraph, a futuristic openworked chronograph shown in two 39mm square-case versions.
- The watch uses the TH80-00 automatic chronograph calibre, running at 5Hz for 1/10th-second timing and fitted with the TH-Carbonspring balance spring.
- Its debut at Watches and Wonders Geneva 2026 matters because it brings TAG Heuer LAB technology into one of the brand’s most recognisable racing watches.
The TAG Heuer Monaco Evergraph is a new technical expression of the Monaco, offered in microblasted Grade 5 titanium or black DLC-coated titanium with an exposed chronograph movement at its centre.
This isn’t a gentle vintage exercise.
TAG Heuer has taken the square Monaco silhouette and pushed it toward a more architectural, almost prototype-like direction, using the dial opening to make the movement part of the design rather than hiding it beneath a conventional face.
A Monaco built around visible mechanics
The 39mm square case keeps the Monaco’s defining footprint, but the Evergraph’s treatment feels deliberately more severe.
Microblasted titanium gives one version a dry, technical finish, while the black DLC model leans harder into the stealth-racing look.
The left-side crown and elongated pushers continue the Monaco’s familiar asymmetry, but the taut case lines and exposed dial create a more modern tension than the classic blue-dial references many collectors associate with the name.
Through the openworked dial, the barrel, gear train and oscillator are all on display, turning the chronograph’s working parts into the visual centre of the watch.
The TH80-00 calibre is the real headline
Inside the Monaco Evergraph is the TH80-00, a self-winding chronograph movement developed by TAG Heuer LAB in La Chaux-de-Fonds with Vaucher Manufacture Fleurier.
Its 5Hz frequency means the movement beats at 36,000 vibrations per hour, allowing the chronograph to measure elapsed time to 1/10th of a second.
That high-frequency approach fits neatly with TAG Heuer’s long chronograph identity, but the more interesting detail may be the TH-Carbonspring.
This carbon composite balance spring is designed to improve magnetic resistance, help absorb shocks and support stable timekeeping, giving the Evergraph a technical talking point that goes beyond openworked styling.
Chronometer certification and daily practicality
The TH80-00 is COSC-certified as a chronometer, which gives the Monaco Evergraph a precision credential to match its exposed engineering.
It also offers approximately 70 hours of power reserve, a useful figure for a modern automatic chronograph and enough to leave the watch aside for a weekend without immediately reaching for the crown.
That combination of high-frequency timing and extended autonomy makes the Evergraph feel less like a concept piece and more like a serious production chronograph with a bold visual language.

Who the Monaco Evergraph is for
The Monaco Evergraph should appeal to collectors who like the Monaco’s motorsport history but want something more technical than a heritage reissue.
It’s also likely to speak to buyers who enjoy skeletonised or openworked watches, provided they prefer a purposeful engineering mood over decorative ornament.
The titanium construction, 1/10th-second chronograph capability and carbon spring technology make this one of the more forward-looking Monaco executions in recent memory.
Its success will depend on how TAG Heuer balances production, pricing and availability, but as a statement of intent, the Monaco Evergraph makes the brand’s chronograph obsession feel current again.
