TL;DR — TAG Heuer Monaco Review: The Monaco is one of the most historically significant watches ever made — the world’s first square automatic chronograph, born in 1969 and immortalised by Steve McQueen in Le Mans. Today’s CBL2111 carries the excellent in-house Calibre Heuer 02 with an 80-hour power reserve, a gorgeous blue sunray dial, and 100 m water resistance. Prices start around $5,950 for the leather-strap version (CBL2111.FC6453) and reach $8,500 for the steel-bracelet model (CBL2111.BA0644) as of September 2026. Bold, polarising, and utterly unique — we rate it 8.5 / 10.

History: Born at Monaco, Made Legendary by McQueen
Few watches carry a biography as rich as the TAG Heuer Monaco. Launched on 3 March 1969 — the same day as the Rolex Daytona made its own headlines — the original Heuer Monaco Ref. 1133 was the world’s first automatic, square-cased chronograph. It was a radical proposition at a time when round watches dominated high watchmaking, and Heuer’s boss Jack Heuer staked the brand’s reputation on it.
The Monaco housed the revolutionary Calibre 11, a breakthrough movement jointly developed by Heuer, Breitling, Hamilton-Büren, and movement specialist Dubois Dépraz. Its automatic winding rotor oscillated to the left — a quirk later exploited for marketing — and the entire mechanism was housed in a 39 × 39 mm square stainless steel case with a crown positioned on the left side rather than the conventional right. Watchmaking convention was being rewritten in real time.
Then came Steve McQueen. When the actor, a devoted motorsport enthusiast, strapped a Monaco Ref. 1133B to his wrist to portray racing driver Michael Delaney in the 1971 film Le Mans, it created the most powerful piece of watch product placement in history. The blue-dialled, square-cased Monaco became “Steve McQueen’s watch,” and that association — genuine, not manufactured — has driven demand for Monaco references for over five decades.
The Monaco was discontinued in 1975 after failing to ignite mainstream commercial success beyond its cult following, but it returned in 1997 following TAG Heuer’s acquisition of the Heuer brand. Today’s CBL2111 is the most technically accomplished Monaco ever made, ditching the ebauche movements of the modern re-editions for a genuine in-house calibre developed entirely within the TAG Heuer manufacture in La Chaux-de-Fonds.

Design & Case: Still Radical After 55 Years
The Monaco’s 39 × 39 mm square case is both its greatest strength and its most polarising feature. In a world saturated with round chronographs, the Monaco stops conversations. The case’s tonneau-adjacent geometry — squared at the corners with subtle chamfering — gives it a presence on the wrist that few watches can match, yet the 39 mm footprint keeps it far from oversized territory.
TAG Heuer’s finishing is excellent. The case alternates between fine-brushed and mirror-polished surfaces, with the crown placed left of centre on the left side of the case — a nod to the original 1969 design, when the unusual positioning was a practical accommodation of the Calibre 11’s movement architecture. The two pushers, however, sit conventionally at 2 and 4 o’clock on the right side.
The sapphire caseback — an upgrade from earlier Monaco re-editions that used solid casebacks — reveals the decorated Calibre Heuer 02 movement in full. Bevelled steel bridges, a black-coated peripheral rotor decorated with the Monaco name, and Côtes de Genève striping make this a case for wearing case-side-down on a glass coffee table as much as wrist-side-up in a meeting.
At 15.21 mm thick, the Monaco is not svelte — this is not a watch that disappears under a dress-shirt cuff — but it sits comfortably on the wrist due to its relatively short lug-to-lug distance. The 22 mm lug width accommodates either the original-style flat bracelet with polished centre links or various leather and rubber strap options.
Movement: Calibre Heuer 02 In-House
This is where the modern Monaco earns serious credibility. Earlier 21st-century Monacos used the Valjoux 7750 — a fine workhorse but an off-the-shelf ebauche that sits awkwardly in a watch at this price point. The CBL2111 changes everything with the Calibre Heuer 02 (technically the TH20-00), developed and manufactured at TAG Heuer’s La Chaux-de-Fonds atelier.
At 31 mm in diameter, the movement is purpose-built for the Monaco’s square case architecture. It beats at 4 Hz (28,800 vph), deploys a column-wheel and vertical clutch for silky-smooth chronograph engagement, and delivers a best-in-class 80-hour power reserve — approximately 3.3 days of autonomy, easily enough to cover a long weekend before requiring a wind. Compare that to the Breitling Navitimer B01’s 70-hour reserve and the improvement is tangible.
The Calibre Heuer 02 is COSC-tested in select references, but even without official chronometer certification the movement is impressively accurate in practice — typically within +/- 4 seconds per day in real-world conditions. The column-wheel mechanism ensures a positive, mechanical click when starting and stopping the chronograph, rather than the mush of a horizontal clutch under heavy spring pressure.
Dial & Legibility
The dial layout is a faithful evolution of the original 1969 configuration. A sunray-brushed deep blue base — arguably the most historically correct choice for a Monaco — provides the backdrop for three silver opaline sub-registers: running seconds at 9 o’clock, a 30-minute chronograph counter at 3 o’clock, and a 12-hour chronograph counter at 6 o’clock. This “tri-compax” layout is classic chronograph architecture.
Rhodium-plated applied baton indices carry white Super-LuminNova, while the chronograph seconds hand is finished in an arresting red lacquer — a nod to the 1969 original and a hugely effective legibility aid. The TAG Heuer logo appears at 12 o’clock in period-correct typography, and a date window sits between 4 and 5 o’clock without disrupting the tri-compax symmetry.
How Does It Wear?
The Monaco is a conversation-starter, full stop. Wearing one is a statement of intent — you’re not choosing a watch that blends in. The 39 × 39 mm square case reads larger than a round 40 mm due to the unbroken visual field of the square, but the relatively modest lug-to-lug depth means it doesn’t perch uncomfortably on smaller wrists.
The steel bracelet variant (CBL2111.BA0644) wears beautifully integrated — TAG Heuer has matched the bracelet taper to the case width thoughtfully — while the leather strap version (CBL2111.FC6453) offers a sportier, more casual proposition. Both configurations allow rubber strap substitution for water and beach use, keeping the 100 m water resistance meaningfully accessible.
Compared to the sister TAG Heuer Carrera Chronograph — a round, more traditional-looking alternative — the Monaco occupies a distinctly different psychological position. The Carrera is refined versatility; the Monaco is deliberate personality. Both use the Calibre Heuer 02, making the choice almost entirely aesthetic and identity-driven.
Competitor Comparison
The Monaco occupies a fascinating position in the luxury sport-chronograph segment — competing with round-cased rivals on specifications while remaining in a category entirely of its own making in terms of design.
| Watch | Case Size | Movement | Power Reserve | Water Resistance | Price (Sep 2026) |
|---|---|---|---|---|---|
| TAG Heuer Monaco CBL2111 | 39 × 39 mm sq. | In-house Cal. Heuer 02 | 80 hr | 100 m | ~$5,950–$8,500 |
| Rolex Daytona 116500LN | 40 mm round | In-house Cal. 4130 | 72 hr | 100 m | ~$16,550 (retail; grey market: $25,000+) |
| Omega Speedmaster Professional | 42 mm round | In-house Cal. 3861 (manual) | 60 hr | 50 m (splash) | ~$6,900 |
| Breitling Navitimer B01 | 43 mm round | In-house Cal. B01 | 70 hr | 30 m | ~$9,200 |
| IWC Pilot’s Chronograph 41 | 41 mm round | In-house Cal. 69385 | 46 hr | 100 m | ~$7,900 |
Against this field, the Monaco’s in-house movement with an 80-hour power reserve stands out. The TAG Heuer Monaco on Amazon shows secondary market activity that confirms robust demand, with pre-owned examples typically trading at 15–20% below retail for recent references in excellent condition.
Value for Money
At $5,950–$8,500 USD, the Monaco sits comfortably in the upper-mid luxury tier where in-house movements, sapphire casebacks, and genuine brand heritage are expected rather than remarkable. Within that context, the Monaco delivers on every front.
The Calibre Heuer 02 is a genuine in-house movement that would pass muster in watches costing 50% more. The 80-hour power reserve is class-leading. The 100 m water resistance is generous. The sapphire caseback and excellent case finishing are appropriate for the price. And crucially, the Monaco is the only square automatic chronograph with this combination of heritage, brand recognition, and movement quality anywhere near this price point.
For collectors, the Monaco offers something the Speedmaster and Daytona cannot: a design that exists completely outside the dominant round-case paradigm, a story that runs from Le Mans to Le Chaux-de-Fonds, and a level of conversation-starting wrist presence that justifies every cent of the premium over a more conventional sport chronograph. Those looking for a luxury chronograph watch at this tier have few alternatives with this level of historical provenance.
The Monaco also holds value well on the secondary market. The in-house Calibre Heuer 02 transition has made earlier ebauche-movement Monacos less desirable in relative terms, meaning the CBL2111 has a logical price floor. The TAG Heuer Aquaracer Professional 300 offers TAG Heuer value at a lower price point, but for those who’ve fallen for the Monaco’s square silhouette, there’s simply no substitute.
Verdict
The TAG Heuer Monaco CBL2111 is not merely a good watch — it’s a historically significant one. In a crowded chronograph market, it offers something genuinely different: a square case with a storied past, an in-house movement that punches well above its price class, and a cultural cachet rooted in genuine motorsport history rather than marketing. For the right buyer — someone who values bold design, deep provenance, and a watch that makes a statement — it’s a near-flawless choice at the price point.
Deducting half a point for the relatively niche aesthetics (the square case is emphatically not for everyone) and a further half for the thickness, which limits formal-wear versatility. But if you’ve already fallen for the Monaco’s iconography, no amount of rational analysis will steer you elsewhere, and that’s exactly how it should be.

Frequently Asked Questions
The TAG Heuer Monaco is famous for being the world’s first square-cased automatic chronograph, launched in 1969. It became a global icon when actor and racing enthusiast Steve McQueen wore a Monaco Ref. 1133B on his wrist throughout the 1971 film Le Mans, cementing its status as one of the most desirable sport watches in history.
As of September 2026, the TAG Heuer Monaco CBL2111.FC6453 (leather strap) retails at approximately $5,950 USD, while the CBL2111.BA0644 (steel bracelet) retails at approximately $8,500 USD. Prices vary by retailer and region. Pre-owned examples of the Calibre Heuer 02 model typically sell for 15–20% below retail in excellent condition.
The TAG Heuer Monaco CBL2111 uses the Calibre Heuer 02 (reference TH20-00), an in-house automatic chronograph movement developed and manufactured at TAG Heuer’s La Chaux-de-Fonds manufacture. It features a 31 mm diameter, 33 jewels, a 4 Hz beat rate (28,800 vph), a column-wheel and vertical clutch for precise chronograph operation, and an outstanding 80-hour (3.3-day) power reserve.
The TAG Heuer Monaco CBL2111 is rated to 100 metres (330 feet / 10 bar) of water resistance — sufficient for swimming and snorkelling, though not for scuba diving. Given its square case geometry and the placement of pushers and crown, most collectors treat the Monaco as a splash-resistant dress-sport watch and prefer not to submerge it regularly.
Steve McQueen wore a TAG Heuer Monaco Ref. 1133B in the 1971 film Le Mans. The Ref. 1133B features a blue dial with white sub-registers, a stainless steel case, and the original Calibre 11 automatic chronograph movement — making the blue-dial Monaco the most historically iconic of all Monaco references. TAG Heuer has released numerous limited-edition “McQueen” tributes over the decades.
Both are iconic chronographs with deep historical narratives — the Monaco from Le Mans, the Speedmaster from the Apollo Moon landings. The Speedmaster Professional uses a manual-wind Cal. 3861 with 60 hours of power reserve and only 50 m water resistance; the Monaco’s automatic Cal. Heuer 02 offers 80 hours of power reserve and 100 m water resistance. The Monaco retails at a similar price (~$5,950–$8,500 vs. ~$6,900 for the Speedy Pro) but is far more visually distinctive with its square case design.
The Monaco holds its value reasonably well in the pre-owned market, particularly the modern CBL2111 references powered by the in-house Calibre Heuer 02. Older Monaco references with Valjoux movements have softened in value as collectors increasingly prefer in-house calibres. Limited-edition Monaco models — especially Gulf-livery and McQueen tributes — can command significant premiums above retail. As with all watches, condition, box, and papers significantly affect resale value.
