Strap for Carrera Calibre Heuer 02T 45 Chronograph Tourbillon Shanghai

The lug width of the TAG Heuer Carrera CAR5A8AC.FT6231 is 20mm. This measurement represents the distance between the two lugs of the case and is essential for selecting a compatible strap. To verify it, measure the internal space between the lugs with a digital calliper: the value must correspond to 20mm to ensure precise installation without mechanical play or forcing.

There is no universal choice, but rather different aesthetic narratives. Alligator leather in soft vegetable tanning creates sophisticated elegance in contrast with the titanium; nappa calf amplifies the formal aspect; technical NATO fabric remains faithful to motorsport origins. Your choice depends on intended use and the chromatic palette you desire: earth-tones for discreet elegance, black for formality, anthracite-grey for sporting authenticity.

Remove the strap using a dedicated tool (spring bar tool) by inserting it into the lateral slot of the case lug. Push gently inward to release the internal spring that supports the pin, then extract the lug from the worn strap. Install the new strap by inserting the metal pin (spring bar) into its designated seats, ensuring both sides are fixed symmetrically. Verify that the strap is stable before wearing the watch.

Yes, 20mm straps from milanostraps.it are fully compatible with the CAR5A8AC.FT6231, as this lug width is the standard required by the case of this model. You can choose from various leather options (alligator, calf, shell cordovan) and customise length, initials and stitching thread according to your preferences.

Longevity depends on leather quality and intensity of use. Premium alligator leather in vegetable tanning, worn regularly (5-6 days per week), maintains structural integrity for 3-5 years before requiring replacement. If used occasionally (1-2 days per week), durability extends to 7 years. Patina and wear marks represent natural evolution, not degradation: well-tanned leather becomes softer and more characterful over time. The Casati Milano atelier provides an 18-month warranty on made-to-order straps.
