Strap for Equestrian 30 Diamond / Roman

The lug width of the Longines Equestrian L6.131.0.71.2 is precisely 14mm. This measurement represents the distance between the two spring bars on the case lugs and determines the width of the strap that can be fitted to the watch. It is essential not to confuse lug width with the overall strap width, which may vary slightly if the strap features a progressive taper towards the buckle.

For the Longines Equestrian L6.131.0.71.2, we recommend alligator leather in C or A grain, particularly in dark brown, châtaigne, or black tones, as the natural texture complements rather than competes with the dial. Alternatively, vegetable-tanned calf leather offers visible patina development over time, whilst shell cordovan provides an excellent balance between elegance and durability. Synthetic materials are discouraged for this dress watch, which demands authentic tactile quality.

To change the strap, remove the spring bars using a spring bar tool. Position the tool in the groove of the spring bar from underneath, gently push upward to compress the internal spring, and extract the bar. Repeat on the opposite side. Align the new 14mm strap with the lugs and reinsert the spring bars firmly until you hear a distinct click, ensuring secure placement.

Yes, you may use high-quality aftermarket straps provided they strictly respect the 14mm lug width and are compatible with the case width. We recommend verifying the technical specifications supplied by the specialist manufacturer and confirming that the strap does not visually exceed the case width. Artisanal leather, alligator, and shell cordovan straps are particularly suited to the elegant character of this timepiece.

The lifespan of a leather strap depends on tanning quality, daily use, and climatic conditions. A high-quality vegetable-tanned leather strap can last between 2 to 4 years with moderate wear, developing a captivating patina over time. Alligator and shell cordovan are more resilient and can last 5 to 6 years or longer with proper maintenance. Prolonged exposure to humidity, excessive heat, and intense perspiration reduces longevity; we recommend alternating straps during summer months and cleaning regularly.
