Strap for Carrera Calibre Heuer 02T 45 Chronograph Tourbillon Polychrome

The lug width is 20 millimetres. This measurement is model-specific and determined by the geometry of the titanium-forged lugs. Always verify this measurement before purchasing an aftermarket strap, by positioning the ruler perpendicularly across the lower lug shoulder.

There is no single ideal choice. The best strap depends on intended use and personal preference. For formal elegance, alligator in cognac or black tones amplifies sophistication. For summer sportiness, a nylon ballistic NATO or vulcanised rubber echoes the aviation heritage. For material exclusivity, shell cordovan offers unparalleled specular patina. The forged carbon case suggests neutral palettes: the strap should support, not rival, the case aesthetically.

The lugs of the CAR5A8AF.FC6415 are equipped with removable spring bars. Use a dedicated spring bar tool to lift the bar from the grooved channel beneath the lug, thereby releasing the strap. Insert the new strap, verifying that the spring bars are correctly seated within the lug channels: positioning must be symmetrical to prevent visual asymmetry.

Yes. Any strap measuring 20 millimetres in width is compatible with the CAR5A8AF.FC6415, provided the spring bars are standard gauge and the material is not excessively rigid (to avoid friction with the forged carbon). Milano Straps offers 20mm straps customisable in leather, rubber and textile, with adjustable sizing and options for initials and stitching thread colour.

Durability depends on intensity of wear, climatic conditions and material selection. A vegetable-tanned leather strap (alligator, calf, shell cordovan) typically lasts 3–5 years of daily wear before restoration or replacement is required. Exposure to perspiration, humidity and ultraviolet light accelerates deterioration. Rubber and nylon ballistic offer superior resilience (5–7 years), but patinate less characteristically than leather. The Casati Milano atelier provides an 18-month guarantee on all custom straps, covering manufacturing defects.
