Strap for Equestrian Horseshoe 34 Roman

The lug width of the Longines Equestrian L6.138.4.71.2 is 16 mm. This measurement refers to the internal distance between the two upper (and lower) attachment points, and it is critical for aftermarket strap compatibility. Proper measurement is performed by placing a digital caliper perpendicular to the two attachment clips, excluding any metallic protrusions.

The optimal strap selection depends on intended use and personal preference. For formal elegance, brown or black alligator is unmatched, boasting fine grain and lustrous finish. Those seeking everyday versatility with natural patina will appreciate shell cordovan, which develops extraordinary aging characteristics. Calf leather with vegetable tanning represents the ideal compromise between sophistication and practicality, adapting comfortably to the wrist. For sporting contexts, NATO fabric or vulcanised rubber ensure maximum water resistance.

Strap replacement requires minimal tools: a caseback opener and a spring bar removal tool. Position the watch with lugs facing upward, locate the micro-pins inside each lug, use the tool to compress the pin downward, and slide out the old strap; insert the new strap by applying gentle pressure until the pin clicks into place. We recommend extreme care to avoid scratching the polished stainless steel case.

Yes, any strap featuring a 16 mm lug width is technically compatible. However, not all straps are constructively suitable: it is essential that the curve of the lug matches the Longines Equestrian's configuration to prevent unusual stress. Bespoke artisanal straps, such as those crafted by Casati Milano, guarantee perfect fit through personalisation of curves and thickness.

Leather strap longevity varies according to material type, usage patterns, and maintenance. Alligator and shell cordovan, being dense and resilient leathers, provide 3–5 years of daily wear. Calf with vegetable tanning typically lasts 2–3 years before requiring replacement, whilst developing a fascinating patina. Prolonged exposure to direct sunlight, perspiration, and humidity accelerates aging; proper storage in a temperate environment and occasional cleaning with specialised products significantly extend lifespan. Casati Milano straps are backed by an 18-month warranty.
