Strap for Equestrian Horseshoe 26 MOP

The lug width of the Longines Equestrian L6.136.4.87.2 is 12mm. This specification is fixed and non-interchangeable with other dimensions: the two attachment pins are precisely 12mm apart. To verify, position a calliper at the widest point of the attachment seat, perpendicular to the case.

For this model, Nile alligator represents the superior architectural choice: the regular grain dialogues perfectly with the linearity of the 26mm case. Alternatively, vegetable-tanned calf offers a patina that evolves naturally over time. Both materials, in dark colourways (black, cognac, burgundy), enhance the elegant proportions of the timepiece.

Remove the watch from its case and place it on a soft cloth. Using a dedicated tool (spring bar tool), compress the small elastic stamper inside the seat and slide the pin outwards. Repeat for both sides. Installation of the new strap follows the reverse procedure: insert the pin, compress with the tool, and allow the stamper to reposition naturally.

Yes, provided the strap has been constructed precisely for a 12mm lug width. Quality aftermarket straps (alligator, calf) maintain manufacturing tolerances that respect this specification. Beware of generic 'semi-elastic' straps: for this elegant watch, constructive precision is essential.

A quality leather strap (alligator, vegetable-tanned calf) has an average lifespan of 4-6 years with moderate daily use. Longevity depends on sun exposure, humidity, and maintenance. A synthetic NATO strap lasts 3-4 years before degradation. Casati Milano guarantees 18 months on bespoke straps, covering manufacturing defects and materials.
