Strap for Clous de Paris 36

The Longines Heritage L2.707.4.16.3 features a lug width of exactly 20mm, measured from inner pin to inner pin. This specification is critical for selecting compatible straps without forcing or lateral movement.

Barenia calf is the most versatile choice: it adapts to formal and daily wear, develops natural patina over time, and harmonises with the 36mm proportions. For formality, vegetable-tanned alligator in dark brown is unmatched. For technical use, burgundy shell cordovan offers natural rigidity and subtle sheen.

The process is straightforward: insert a strap removal tool or thin screwdriver into the lateral grooves of the case and apply light pressure to lift the spring pin. Extract the pin completely, remove the old strap, align and insert the new strap, then reinserting the pin. Avoid hammers: the pins are impact-sensitive.

Yes, provided it respects the 20mm lug width specification. An artisanal strap in premium leather or shell cordovan is entirely compatible and often offers superior ergonomics and patina development compared to OEM straps. Verify the strap has been manufactured to these standards.

Durability varies by material and use. Barenia calf or vegetable-tanned alligator, worn regularly and given minimal care (natural air-drying after rain, annual balm treatment), lasts 5-8 years. Shell cordovan lasts even longer. A cotton NATO resists beyond 10 years. Care influences longevity more than natural wear.
