The TAG Heuer Monaco is a square-cased automatic chronograph that Heuer introduced in 1969, and it is best known for its association with Steve McQueen in the 1971 film Le Mans. Today it comes in two main movement generations: the older Calibre 11 models and the newer in-house Calibre Heuer 02 models. This guide explains the history, how to tell the versions apart and what to check before you buy one. Bizak & Co. is a sourcing desk, not an authorised TAG Heuer retailer, and the watches discussed here are sourced to order rather than held in stock.

What is the TAG Heuer Monaco?
The Monaco is a square chronograph that was launched in March 1969 as the Monaco Chronomatic, according to TAG Heuer's own magazine. Its unusual shape was the point: a square case that still met Heuer's water-resistance standard was hard to achieve, and the brand credits its case supplier Piquerez with solving it. The crown sits on the left side, a layout tied to the original automatic chronograph movement. Since then the name has returned in many reissues, limited editions and colorways, which is why references can look similar and differ in important ways.
Why is the Monaco linked to Steve McQueen?
McQueen wore a Monaco in the 1971 racing film Le Mans, and that screen appearance made the watch a pop-culture icon. Accounts say the choice was influenced by Jo Siffert, the racing driver who was a Heuer ambassador and advised on the production; McQueen's racing suit carried Heuer branding. Details differ between sources, including which Heuer model McQueen first wanted and how many watches were used on set, so treat the neat version of the story with caution. What is documented is that watches from the film have sold at auction, and that TAG Heuer has made McQueen-linked editions of the Monaco since.
What is the Calibre 11, and why does it matter?
Calibre 11 is the automatic chronograph movement of the original Monaco generation. TAG Heuer's history describes it as the product of a joint effort known as Project 99, involving Heuer, the complications specialist Dubois-Dépraz and the movement maker Buren, with Hamilton joining after it acquired Buren. Modern Calibre 11 watches are reported to use a Sellita base with a chronograph module, rather than the 1960s original, so a recent "Calibre 11" is not the same machine as a vintage one. On those modern models the chronograph module is stacked on the base movement, which is one reason some collectors prefer the integrated, in-house Heuer 02.
Calibre 11 or Heuer 02: which Monaco should you choose?
Choose the Heuer 02 if you want a modern in-house column-wheel chronograph with a long power reserve, and the Calibre 11 if you prefer the classic-era layout and often a lower entry point on the pre-owned market. The Heuer 02 Monaco arrived around 2019, according to watch media, and TAG Heuer lists an 80-hour power reserve for the 39 mm model. The table compares the two generations; confirm the exact figures for any reference you are considering, because limited editions can differ.
| Feature | Calibre 11 Monaco | Calibre Heuer 02 Monaco |
|---|---|---|
| Movement type | Automatic chronograph, base plus chronograph module | In-house automatic column-wheel chronograph |
| Typical case size | About 39 mm square (the 1969 original was smaller) | 39 mm square |
| Power reserve | Shorter; check the specific reference | 80 hours (brand listing for CBL2111 variants) |
| Water resistance | Varies by reference | 100 m |
| Frequency | Check the specific reference | 28,800 vph (4 Hz) |
| Example references | CAW211R, CAW211P | CBL2111, CBL2116 |
Which Monaco dial colors are most popular?
Blue and green are the most recognisable Monaco dial colors, with black and other special-edition dials appearing more occasionally. The blue dial is the classic nod to the McQueen watch. Green is a newer, more distinctive option, and the TAG Heuer Monaco CBL2116.FC6497 with a green index dial is an example of a Heuer 02 reference in that color. Dial finish, markers and chapter ring vary between references, so compare photographs of the exact reference rather than judging by color name alone.
What size is the Monaco, and does it wear large?
The modern Monaco is 39 mm square, and it wears like a slightly larger round watch because the corners and lugs add visual width. The original 1969 case was smaller, and reissues have generally stayed close to the 39 mm mark. If you have a small wrist, check the lug-to-lug measurement of a specific reference, since the square shape makes diameter figures less informative than they are for a round case.
Steel, gold or titanium: which Monaco materials exist?
Stainless steel is the standard and the most common material, and it is what the references discussed here use. TAG Heuer has also released Monaco editions in other materials, including precious-metal and lightweight options, usually as limited or special runs, so confirm the case material in the reference listing before you commit. Steel models may come on a leather strap or a steel bracelet; the CBL2111.BA0644 is the bracelet version of the blue Heuer 02, while the CBL2111.FC6453 is on leather.
What should you check before buying a Monaco?
- The reference number. Match it to the movement generation you want, Calibre 11 or Heuer 02, because the names and looks overlap.
- Edition and dial. Limited editions, Gulf-style liveries and McQueen-linked versions are separate references; confirm which one you are being offered.
- Condition and service history. Ask for recent service records on pre-owned examples, and check the case corners and crystal for wear, since square cases show polishing more than round ones.
- Box, papers and strap. A complete set helps on resale, and original strap and buckle details matter.
- Authenticity. See our authenticity page for what we check and what our buyer-protection terms cover.
