Frequently asked questions

What is the lug width of the Longines Equestrian L6.135.4.87.2?

The lug width of the Longines Equestrian L6.135.4.87.2 is 10mm. This dimension is crucial for selecting compatible straps: any strap designed for this model must have lugs spaced precisely 10mm apart. You can verify compatibility by measuring the internal distance between the two lug pins with a digital calliper.

What is the best strap for the Longines Equestrian L6.135.4.87.2?

The optimal strap depends on usage and aesthetic preference. Alligator is the classic choice for formal elegance: its regular grain and fine texture complement the 23mm case perfectly. Shell cordovan is ideal if you seek durability and a rich red patina that develops over time. Taurillon calf offers a softer, more versatile alternative. For a contemporary approach, natural rubber or technical textile straps add versatility without compromising the watch's stylistic balance.

How do I change the strap on my Longines Equestrian L6.135.4.87.2?

Strap replacement is straightforward: place the watch on a soft surface (microfibre cloth) and locate the lateral lug pins connecting the strap to the case. Using a spring bar tool, gently push the internal spring of the pin downward to release one strap end. Repeat on the other side. To install the new strap, insert the lug pin through the new strap's lug and then through the case holes, ensuring the spring clicks properly into place. If you lack experience, entrust this task to a professional to avoid damage.

Can I use aftermarket straps compatible with the Longines Equestrian L6.135.4.87.2?

Yes, absolutely. High-quality aftermarket straps, such as those available on milanostraps.it with 10mm lug width, are often superior to original straps in terms of materials and craftsmanship. The key is selecting straps certified for this specific lug width and verifying that the pin diameter is compatible with the case. A well-crafted aftermarket strap not only enhances aesthetic value but also offers greater versatility and personalisation possibilities.

How long does a leather strap last on a Longines Equestrian?

Durability varies based on material and usage intensity. A properly maintained alligator strap lasts 4-6 years with daily wear. Shell cordovan is more durable, often exceeding 7-8 years thanks to leather density and resistance. Taurillon calf has an average lifespan of 3-5 years. Maintenance is essential: avoid prolonged water exposure, occasionally apply leather-specific balm, and allow natural air drying away from heat sources. With vegetable tanning, the developing patina is not wear but acquired character, further extending the strap's useful life.
