Strap for Carrera Connected Modular 45 Titanium / Ceramic / Electric Blue Rubber

The lug width of the SBF8A8001.11FT6118 is precisely 20mm. This dimension was calculated by TAG Heuer to maintain correct visual proportions between the 45mm case diameter and the strap, ensuring wrist comfort without appearing disproportionate. To measure the lugs correctly, position a calliper or ruler in the internal groove where the spring bar rests, measuring from wall to wall perpendicular to the watch's longitudinal axis.

For the 45mm titanium and ceramic Carrera, the following are advised: alligator with vegetable tanning for formal settings, offering elegance and natural patina development; calf leather for humid or sports environments, thanks to density and water-resistance; NATO canvas or linen for intense activities and aggressive environments; FKM rubber for chemical resistance and maximum grip. The choice depends on primary usage context and desired formality level.

To change the strap, remove the two lateral spring bars using a dedicated extraction tool. Position the tool in the case's lateral hole, gently push inward to release spring tension, then extract the spring bar. After removing the old strap, align the new strap's holes and reinsert the spring bars into the lugs, ensuring they click securely. Milano Straps offers dedicated guidance to ensure correct execution without risk of case damage.

Any 20mm strap conforming to international standards is compatible. Milano Straps provides a 20mm strap collection specifically tested on cases of this calibre, guaranteeing millimetre-perfect fit without lateral play. Compatibility is assured by the nominal lug hole diameter; however, to maximise comfort and case protection, choose validated models rather than generic solutions not specifically engineered for this reference.

Leather strap longevity depends on tanning method and material. An alligator strap with vegetable tanning resists 18–24 months of daily wear, developing natural patina that enhances aesthetics; superior calf leather reaches 20–28 months due to higher density. NATO canvas straps exceed 36 months as they are synthetic. Milano Straps guarantees 18 months on all straps created by the Casati Milano atelier, with option for regeneration via maintenance tanning.
