Strap for Carrera Calibre Heuer 02 45 Black Ceramic / Skeleton / Rubber

The lug width is exactly 20mm. This measurement is taken by positioning a calliper between the two spring bar pins that attach the strap to the case. It is essential to verify this measurement before purchasing an aftermarket strap to avoid incompatibility issues.

For a chronograph of this calibre, alligator or shell cordovan represent the most refined choices. Alligator develops a noble patina over time, whilst cordovan offers superior resistance and exceptional longevity. For more sporting use, a rubber or NATO fabric strap guarantees practicality without aesthetic compromise.

The process requires a specialised tool (spring bar remover) to remove the elastic pins from the case lugs. Position the chronograph on a stable surface, insert the tool under the pin until the spring disengages, then withdraw the old strap. Insert the new strap by aligning the holes and press the pin until it clicks. Avoid forcing to prevent case damage.

Yes, any strap with a 20mm lug width is compatible. Quality aftermarket straps often offer greater aesthetic flexibility and comfort than factory options. Ensure the strap is made from robust materials such as alligator, shell cordovan or vegetable-tanned leather to guarantee durability.

A high-quality leather strap, whether in alligator or shell cordovan, typically lasts 3–5 years with daily wear, depending on humidity and perspiration exposure. Vegetable-tanned leather tends to last longer than chrome-tanned calf. Proper maintenance – drying the strap after perspiration and rotating between multiple straps – significantly extends longevity.
