Strap for Equestrian 23.5 Diamond / Arabic

The lug width of the Longines Equestrian L6.129.0.73.2 is 10mm. This measurement refers to the internal distance between the two side lugs of the case and is essential for ensuring proper strap compatibility. A 10mm lug width reflects the specific proportions of this 23.50mm diameter model, maintaining aesthetic harmony and wearing stability.

For a Longines Equestrian L6.129.0.73.2, alligator leather with vegetable tanning represents the most coherent construction choice: it offers natural texture, develops personal patina over time, and breathes comfortably on the wrist. Alternatively, shell cordovan guarantees chromatic solidity and deep lustre that dialogues excellently with the satin-finished stainless steel case. French calf remains the path of tactile softness, ideal for those preferring immediate comfort.

Strap replacement is accomplished by extracting the spring bars that connect the strap to the case lugs. Use a dedicated tool (spring bar tool) or a small flathead screwdriver to gently push the bar downward, releasing one end of the strap. Subsequently, insert the new strap and release the bar. For repeated operations, it is advisable to consult a professional watchmaker to avoid damage to the lugs.

Yes, the Longines Equestrian L6.129.0.73.2 fully supports aftermarket straps created by specialised craftspeople, provided they strictly respect the 10mm lug width and are equipped with spring bars of equivalent construction quality. Italian brands such as Milano Straps offer compatible straps customisable in leather, colour and thread, or bespoke services through ateliers such as Casati Milano.

The lifespan of a leather strap depends on construction quality and intensity of use. A quality alligator or cordovan guarantees 3-5 years of ordinary use, with the possibility of replacing the buckle if necessary. Natural calf tends to wear more quickly (2-3 years), whilst textile NATO can exceed 7-10 years. Vegetable tanning, owing to the absence of synthetic polymers, also permits restoration and retouching without loss of aesthetic quality.
