Strap for Equestrian Horseshoe 30 Diamond / MOP

The lug width of the Longines Equestrian L6.137.0.87.2 is 14mm. This measurement is constant across all examples of this model and determines compatibility with specific straps. To verify it, measure the distance between the two attachment pins of the case, excluding the case material itself. A strap with incorrect lug width will not fit properly and could compromise both the aesthetics and security of the timepiece.

For the Longines Equestrian L6.137.0.87.2, noble materials are recommended that respect the elegant identity of the model. Alligator with vegetable tanning is the classic choice: its fine natural grain enhances formal sophistication without competing with the mother-of-pearl dial. Smooth calf (box calf) offers softness and versatility, whilst shell cordovan with vegetable tanning imparts character and authentic patina over time. Solutions in natural rubber or NATO are also compatible, though they require stylistic sensitivity to maintain the aesthetic balance of the piece.

To change the strap on the Longines Equestrian L6.137.0.87.2, you will need specific tools: a springbar tool and a stable, well-lit work surface. Locate the springbar pins on the sides of the case between the two attachment points (lugs). Use the springbar tool to gently compress the internal spring of the pin, allowing removal of the old strap. Then insert the new strap into the same holes, ensuring that the pin clicks correctly into position. If you are not experienced, we recommend entrusting this operation to a qualified watchmaker to avoid damage to the case.

Any strap with a 14mm lug width is compatible with the Longines Equestrian L6.137.0.87.2. In Milano Straps' online catalogue, you will find 14mm straps in various materials (alligator, calf, shell cordovan, rubber) and colours, ready for shipment and customisable in sizes, initials and stitching thread. For a complete bespoke experience with personal leather selection and direct consultation, the Casati Milano atelier creates custom straps with an 18-month warranty.

The durability of a leather strap for the Longines Equestrian L6.137.0.87.2 depends on the material, tanning and daily use. A high-quality alligator or calf strap with vegetable tanning can last 5-10 years with proper maintenance (periodic cleaning, natural drying, protection from excessive water and heat). Shell cordovan, if well cared for, can exceed 10 years. Durability is reduced if the strap is subjected to constant moisture, frequent perspiration or prolonged direct sunlight. Milano Straps offers an 18-month warranty on custom straps, guaranteeing material and construction quality.
