Frequently asked questions

What is the lug width of the TAG Heuer Carrera CAR2A91.FT6121?

The lug width of the TAG Heuer Carrera CAR2A91.FT6121 is 20 millimetres. This measurement represents the vertical space between the case lugs where the strap is fitted. The spring bars themselves have a standard diameter of 1.5 millimetres. To verify this measurement on your watch, position a ruler along the inner side of the case between one lug and the other: the result must correspond exactly to 20 millimetres.

What strap is most suitable for the TAG Heuer Carrera CAR2A91.FT6121?

For the CAR2A91.FT6121 we recommend primarily an alligator strap in black with a stainless steel deployante clasp, which combines the natural texture of leather with the contemporary character of the ceramic case. Valid alternatives include vegetable-tanned calf in anthracite grey, which develops a natural patina over time, or a NATO in grey technical canvas for more informal daily use. The choice depends on your lifestyle and occasions of wear.

How do you change the strap on a TAG Heuer watch?

To change the strap on your TAG Heuer Carrera, you will use a specific tool called spring bar pliers or a spring bar tool. Position the watch on a soft surface to avoid scratches. Insert the spring bar tool under the lug pin, exerting light pressure to compress the internal spring of the pin. Once the pin is released from the old strap, extract it completely. Then insert the new strap through the lateral holes of the case, ensuring that the pin clicks correctly into position. Repeat the operation on the other side. If you are not experienced, we recommend contacting an expert such as the Casati Milano atelier.

Is an aftermarket strap compatible with the TAG Heuer Carrera CAR2A91.FT6121?

Yes, any strap with a 20-millimetre lug width is compatible with the TAG Heuer Carrera CAR2A91.FT6121. All artisanal straps produced by Milano Straps respect this standard width and are constructed to fit perfectly with the case lugs. Compatibility is therefore guaranteed regardless of the material chosen, whether alligator, calf, shell cordovan or technical canvas.

How long does a natural leather strap last on a TAG Heuer Carrera?

The lifespan of a natural leather strap depends on daily usage, exposure to moisture and the type of tanning used. A robust calf strap or quality artisanal alligator maintains structural integrity for 4-7 years under normal use conditions. A shell cordovan strap, thanks to the density of the fibre, can exceed 10 years. Continuous exposure to moisture, perspiration and UV rays reduces these timeframes. The Casati Milano atelier provides an 18-month warranty on all handmade straps, covering manufacturing defects and premature wear.
