Strap for Equestrian 23.5 Double Diamond / MOP

The Longines Equestrian L6.129.0.89.2 features a lug width of 10mm. This non-standard dimension is characteristic of this model and represents the distance between the two lugs on the case where the strap attaches. To verify personally, simply measure with a ruler the gap between the two attachment points. It is essential to confirm the correct lug width before purchasing an aftermarket strap.

The optimal strap depends on occasion and personal preference. For formal elegance, an authentic alligator strap in brown or black with vegetable tanning represents the most sophisticated and durable choice. For daily versatility, vegetable-tanned calf leather offers comfort and develops natural patina over time. For sporty occasions, a rubber or NATO fabric strap maintains the minimalist profile of the watch. Regardless, the strap must be compatible with the 10mm lug width.

Changing the strap requires care but is straightforward. Position the watch with the case facing upward, locate the small metal springs (spring bars) holding the strap to the lugs, then use a dedicated tool (spring bar tool) to compress the spring and extract the strap from the lug. Install the new strap by reversing the process, ensuring the spring bar is correctly positioned on both attachment points. If inexperienced, consult a professional watchmaker.

Only straps specifically manufactured with a 10mm lug width are compatible. Milano Straps offers a dedicated collection of 10mm straps in alligator leather, vegetable-tanned calf, shell cordovan, and technical rubber. Always verify that the strap is labelled as compatible with 10mm lugs and that the passants are correctly dimensioned for this feminine model's proportions.

Durability depends on material and usage. An alligator or shell cordovan strap with vegetable tanning, subjected to proper maintenance (gentle cleaning and occasional conditioning), can last 5-10 years or beyond. Vegetable-tanned calf typically lasts 3-5 years under regular use. Natural rubber maintains elasticity for 2-4 years. Factors including humidity, direct sunlight exposure, and frequency of wear significantly influence longevity.
