Strap for Carrera Calibre 5 39 Stainless Steel / Black / Alligator

The lug width is 20 millimetres. This specification is essential when purchasing compatible aftermarket straps. You can verify it by measuring the distance between the two attachment holes on the case, or by consulting the original certificate of authenticity or documentation.

We recommend alligator leather (with regular grain and evolving patina), vegetable-tanned calf (for conscious aesthetics), shell cordovan (exceptionally durable), and rubber/NATO fabrics for sports contexts. Your choice depends on daily usage and personal style preferences.

Removing the strap requires specific tools: a spring bar tool and gentle pressure to release the springs holding the strap to the lugs. If you are not experienced, we recommend entrusting the operation to an authorised centre or specialised atelier, which will also verify correct clasp closure.

Yes, any strap with a 20mm lug width is mechanically compatible. However, consider the aesthetics: materials, thickness, and design must reflect the sporty spirit and proportions of the 39mm case. Not all 20mm straps offer the construction quality appropriate for a TAG Heuer.

A high-quality leather strap (alligator, calf, shell cordovan) lasts 3–5 years with daily use and proper maintenance: avoid prolonged exposure to chlorinated water, protect from direct light, and occasionally apply specialist balm. Natural wear and patina are part of the charm; rubber straps resist longer in humid or aquatic environments.
