The Heritage

The Monaco was introduced in 1969 as the world's first automatic chronograph with a square case. It is equipped with the Chronomatic 15 caliber with hour, minute, small seconds and chronograph functions. The 1533G reference features the distinctive square case shape that differs from the traditional round timepieces of the era.

FAQ

What is the lug width of the TAG Heuer Monaco 1533G?

The lug width of the TAG Heuer Monaco 1533G is 20 millimetres. This measurement is the distance between the two lateral lugs where the strap attaches to the case. It is an exact specification, not an approximation, and must be precisely 20mm to ensure correct aesthetic and functional compatibility.

Which strap is most suitable for the TAG Heuer Monaco 1533G?

We recommend an alligator strap with vegetable tanning for a luxurious, timeless result, or shell cordovan leather for those seeking a patina that develops over time. If your Monaco retains a sporting vocation, a nato strap with characteristic texture is the choice most coherent with the original chronograph character of the model.

How do I change the strap on my TAG Heuer Monaco 1533G?

Strap replacement requires a specific tool to remove the spring bars that attach the strap to the case. You may entrust this to a professional watchmaker or, if experienced, procure a spring bar tool. Remember that the 20mm lug width is inflexible: the new strap must have exactly this measurement. Our Casati Milano atelier offers installation service and expert consultation.

Is an aftermarket strap compatible with the TAG Heuer Monaco 1533G?

Yes, but only if the lug width is exactly 20 millimetres. A quality aftermarket strap, crafted by a specialised artisan, guarantees perfect compatibility and often exceeds the construction standards of original straps, especially regarding leather selection and bespoke stitching.

How long does a leather strap last on the TAG Heuer Monaco 1533G?

The lifespan of a leather strap depends on material quality, frequency of use, and environmental conditions. A quality alligator or vegetable-tanned calf leather can last 5-7 years of regular wear. Our Casati Milano guarantee covers 18 months from creation, and we offer restoration service for straps requiring maintenance.
