Strap for Equestrian Horseshoe 26 Black

The lug width of the L6.136.4.57.0 is 12 millimetres. This is a rare measurement in contemporary watchmaking, reserved for proportioned ladies' models originating from the vintage era. To verify, measure the internal space between the lugs with a ruler: the value should correspond precisely to 12 mm. A compatible strap will have a nominal width of 11.5 or 12 mm to slide smoothly around the spring bars.

Alligator represents the choice of aesthetic excellence: the natural texture and fine grain enhance the sophistication of the dial without competing for attention. Shell cordovan constitutes an alternative of equal merit if you prefer leather with more pronounced tactile history and authentically evolving patina. For intensive use or humid environments, vegetable-tanned calf in fine grain offers practicality without visual compromise. NATO straps reference authentically British equestrian codes. Vulcanised rubber represents the most practical solution for genuine equestrian activities.

Strap replacement occurs via the spring bars, small metal protrusions located at the case extremities. Position the watch on a soft surface (cotton cloth). Use a dedicated tool (spring bar tool) or the blunt end of a Swiss knife to exert light pressure on the pin until the internal spring releases. Extract the pin from the case. Replace the strap by positioning the new pin in the same location and press until you hear a click. Do not force: the pin must not deform.

Yes. Since the Longines Equestrian features a 12 mm lug width, it is possible to adapt bespoke straps constructed to this specific width. Milano Straps offers a dedicated collection of 12 mm straps in various leathers (alligator, cordovan, calf) and finishes, with customisation in length, initials and choice of stitching thread. The Casati Milano atelier permits further customisation through direct consultation and extended warranty.

Durability depends on material and intensity of use. An alligator or shell cordovan strap with vegetable tanning easily reaches 5–7 years of daily wear before requiring replacement. Natural calf has slightly shorter lifespan (3–5 years) in very humid environments. NATO straps in cotton or silk resist 2–4 years depending on sun exposure and humidity. Vulcanised rubber lasts 4–6 years before losing elasticity. Regular care (gentle cleaning, drying, storage away from direct heat) significantly prolongs strap life.
