The TAG Heuer Monaco ref. 1133B is not merely a watch; it is a cultural artifact. Born in 1969 alongside the Caliber 11 automatic chronograph movement, it was the world's first square water-resistant automatic chronograph, and it famously graced the wrist of Steve McQueen in the 1971 film Le Mans. For the trust-fund-baby collector who understands that provenance drives value, the 1133B is a cornerstone piece — a tangible connection to the golden era of motorsport and a blue-chip asset in any serious watch portfolio.

In the current market, the 1133B occupies a fascinating position. While modern Monaco references are readily available at retail, the vintage 1133B — particularly in its original 'McQueen' blue dial configuration — has seen steady appreciation, driven by its rarity, historical significance, and the enduring allure of the square case. This is not a watch for the faint of heart or the thin of wallet; it is a statement piece that demands attention and rewards patience.

This review will dissect the 1133B from an investment perspective: its movement, its wearability, its market trajectory, and its place among its peers. We will analyze whether this is a 'hold' or a 'flip' in the current climate, and why it remains a non-negotiable for the discerning collector who understands that true style is timeless — and profitable.

Manufacture History

Founded in 1860 by Edouard Heuer in St-Imier, Switzerland, TAG Heuer has been synonymous with precision timing in motorsport for over a century. The Monaco, launched in 1969, was a radical departure from traditional watch design, featuring a square case and the groundbreaking Caliber 11 automatic chronograph movement — a collaboration with Breitling, Hamilton, and Buren. The 1133B reference, produced from 1969 to the mid-1970s, is the most iconic iteration, made famous by Steve McQueen.

Movement

The Caliber 11 (also known as Chronomatic) is a modular automatic chronograph movement, with the microrotor mounted off-center and the crown on the left side of the case — a signature of the Monaco. While not in-house, it is historically significant as one of the first automatic chronograph calibers. Finishing is industrial, as expected from a tool watch of the era. The movement beats at 19,800 vph, with 17 jewels and a 40-hour power reserve. It is not COSC certified, but it was never intended to be — it was built to be robust and reliable for the racetrack.

Wrist Feel

The 1133B wears surprisingly well given its square dimensions. The 39mm case sits flat on the wrist, and the short 45mm lug-to-lug ensures it doesn't overhang on smaller wrists. The weight is substantial but not punishing — around 80 grams on the original leather strap. The left-side crown is a conversation starter, but it never digs into the wrist. The acrylic crystal is prone to scratches but adds to the vintage charm. This is a watch that feels purposeful, like a vintage racing helmet: not for everyone, but for those who get it, it's perfect.

Accuracy

Expect +10 to +20 seconds per day in a well-serviced example. The Caliber 11 was not built for COSC precision, and its 19,800 vph beat rate is low by modern standards. However, for a 50-year-old movement, this is acceptable. A full service can bring it closer to +5 seconds, but chasing accuracy on a vintage piece is missing the point. Wear it for the soul, not the specs.

Occasions and Wrist Presence

The 1133B is surprisingly versatile: it works for daily wear, sport (if you're careful with the acrylic crystal), and even dress occasions if paired with a nice leather strap. Its wrist presence is a 5/5 — the square case and blue dial demand attention. This is not a subtle watch. It announces itself with the confidence of a vintage race car — loud, proud, and unmistakably cool.

Reference Variants

1133B: Blue dial with horizontal stripes, red chronograph hand — the Steve McQueen 'Monaco'.
1133G: Gray/black dial, rarer but less iconic.
1133: Silver/white dial, least common of the series.

Investment Value

The 1133B is a tier-one vintage collector's piece. It has appreciated steadily over the past decade, and with the continued interest in vintage motorsport watches, it will likely continue to climb. A Steve McQueen-owned example sold for $220,000 at Phillips in 2020. Standard examples in excellent condition have achieved $25,000-$35,000 at auction in 2023. The pre-owned range is $15,000-$40,000, depending on condition, originality, and provenance. Our recommendation: hold. Do not flip unless you need liquidity.

Service Interval

Service every 5 years, costing approximately $600-$800. Parts are scarce but available through specialized suppliers. Authorized service is not required, but use a reputable vintage Heuer specialist.

Final Verdict

The TAG Heuer Monaco ref. 1133B is not just a watch; it's a trophy. It's for the collector who understands that true value lies in history, design, and scarcity. It is not a daily beater, but a piece to be worn on special occasions — or simply admired in the safe. If you can afford the entry fee, buy it, hold it, and watch it appreciate. This is a blue-chip asset in the world of horology.
