Frequently asked questions
What is the lug width of the Longines Equestrian L6.135.0.57.0?
The lug width of the Longines Equestrian L6.135.0.57.0 is 10 millimetres. This is an ultra-reduced dimension, characteristic of high-end ladies' timepieces. Measurement must be carried out with a digital calliper, positioned perpendicularly across the lugs, from the inner base of one lug to the other, excluding any protrusions from the case or passants. Every tenth of a millimetre is significant to ensure correct strap compatibility.
Which strap is recommended for the Longines Equestrian L6.135.0.57.0?
For the Longines Equestrian L6.135.0.57.0, several options are recommended depending on lifestyle and aesthetic preferences. Alligator in dark brown, taupe, or navy blue represents the most refined choice, with a natural texture that amplifies the sense of luxury. Vegetable-tanned calf leather offers a contemporary alternative with a patina that develops naturally over time. For those seeking everyday versatility, a high-density NATO strap in neutral colours such as cream white or stone grey is pragmatic and does not diminish the delicate proportions of the watch.
How do I change the strap on the Longines Equestrian L6.135.0.57.0?
The strap of the Longines Equestrian L6.135.0.57.0 is changed by disengaging it from the lugs using a specific tool (springbar remover). Position the watch on a soft, stable surface, then gently insert the forked screwdriver under the spiral spring that secures the lug pin. Press lightly to widen the spring and slide the old strap out from under the pin. Repeat on the other lug. Insert the new strap, aligning it with the lugs, and press the pin until the spring re-engages. Ensure the strap is securely fastened before wearing the watch.
Can I use an aftermarket strap for the Longines Equestrian L6.135.0.57.0?
Yes, you can use a quality aftermarket strap for the Longines Equestrian L6.135.0.57.0, provided the lug width is exactly 10 millimetres. Aftermarket straps offer great stylistic customisation and often feature high-quality materials (alligator, calf, shell cordovan) at more accessible prices than original Longines straps. Milano Straps provides artisanal straps specialised in this size, fully customisable in leather, colour, stitching and initials. We always recommend verifying the lug width with a calliper before ordering to avoid incompatibility.
What is the average lifespan of a leather strap for the Longines Equestrian L6.135.0.57.0?
The lifespan of a leather strap for the Longines Equestrian L6.135.0.57.0 varies based on material, use and maintenance. An alligator or quality calf strap, worn daily, has an average lifespan of 4-6 years before requiring replacement. Alligator with vegetable tanning tends to last longer, developing a fascinating patina over time. Factors such as moisture exposure, perspiration, UV rays and frequency of use influence longevity. To extend the lifespan, avoid prolonged water immersion, store the watch in a dry, air-conditioned environment, and occasionally apply a protective balm specifically designed for fine leathers. Milano Straps artisanal straps come with an 18-month guarantee and can be serviced at the Casati Milano atelier.
