Strap for Equestrian 26.5 Double Diamond / MOP

The lug width of the Longines Equestrian L6.130.0.89.2 is 12mm. This is a non-standard measurement, smaller than the more common 14mm and 16mm widths. To verify, place a ruler perpendicular to the case at the attachment level: the distance between the inner edges of the lugs must correspond exactly to 12mm. This specificity is critical when selecting a strap, as a measurement error results in improper or dangerous attachment.

For the Equestrian model, satin alligator is the primary aesthetic choice: the natural texture of the scutes dialogues magnificently with the satin-finished stainless steel case, creating tactile and visual harmony. Noble alternatives include vegetable-tanned calf leather (which develops patina over time) or shell cordovan for enthusiasts of structured materials. For equestrian sport contexts, a NATO strap in fabric or high-quality FKM rubber offer practicality whilst maintaining sartorial elegance.

The change requires a spring bar tool or, alternatively, a small flathead screwdriver. Position the tool in the lateral slot of the case pin or on the strap anchoring ring, apply gentle outward pressure to release the pin spring, extract the pin and slide off the old strap. Insert the new strap aligning the holes with the lugs, reinsert the pin ensuring it is fully engaged. This operation is recommended at a specialist atelier to prevent damage.

Yes, any strap with a 12mm lug width is structurally compatible. However, compatibility does not imply aesthetic coherence. Milano Straps' straps, designed for the case depth and elegant profile of Longines ladies' models, guarantee not only correct mechanical attachment but also stylistic dialogue with the satin-finished steel case and Longines L152 calibre. A personalised clasp completes the wearing experience.

Longevity depends on the material, frequency of wear and environmental exposure. High-quality alligator or calf leather with vegetable tanning ranges between 5 and 8 years of regular use. Natural leather patinas and hardens over time, developing character. Factors such as humidity, direct sun exposure and perspiration accelerate wear. The Casati Milano atelier supplies straps with 18-month warranty and offers regeneration and restoration services to extend the functional life of the piece. Rotating between at least two straps significantly prolongs overall durability.
