Strap for Record 40mm Samaritaine Paris

The lug width of the Longines Record L2.821.4.19.2 is 20mm. This width is standard for many classic mid-sized timepieces and was selected to maintain balanced visual proportions relative to the 40mm case diameter. The measurement should be taken between the inner points where the strap connects to the case, parallel to the case axis.

For the L2.821.4.19.2, straps in alligator leather with vegetable tanning represent the optimal choice, thanks to their regular grain that pairs perfectly with the model's formal minimalism. Alternatively, calf box offers sobriety and moisture resistance, whilst shell cordovan adds chromatic richness and aesthetic evolution with wear. For summer use, natural rubber straps maintain formal coherence.

Strap replacement is performed using a spring bar removal tool to extract the pins connecting the strap to the case. One must gently release the pin from its lower seat, lift the strap, and insert the new one. It is advisable to work on a soft surface (microfibre cloth) to avoid scratching the case, and to procure a dedicated quality tool rather than improvised alternatives.

Yes, any strap with a 20mm lug width is compatible with the L2.821.4.19.2, provided the strap's construction quality is adequate to support the weight and use of the timepiece. Hand-crafted straps in premium leather, made with hand construction and sartorial finishes, guarantee superior durability and aesthetics compared to standard factory straps.

The lifespan of a natural leather strap depends on frequency of use, environmental conditions, and leather quality. A strap in alligator or shell cordovan, with vegetable tanning and sartorial construction, maintains structural integrity for 3–5 years of daily wear. Patina and slight shoulder thinning are natural signs of ageing, not deterioration. Regular maintenance (occasional cleaning with a damp cloth) extends useful life.
