Strap for Equestrian 23.5 MOP

The lug width of the Longines Equestrian L6.129.4.87.2 is 10 millimetres. This measurement is critical for selecting the correct strap: a width that is too large appears disproportionate relative to the 23.5 mm case diameter, whilst a width that is too narrow will not fit correctly on the lugs. Always verify this dimension by measuring between the horizontal lugs with a digital calliper before ordering a new strap.

The ideal strap choice depends upon intended use and aesthetic preference. For formal occasions, we recommend alligator with vegetable tanning in cognac brown or black, which develop naturally over time. For daily versatility, smooth calfskin offers ease of maintenance whilst retaining artisanal quality. For equestrian sport or humid environments, technical rubber in black guarantees superior grip and durability. All straps compatible with 10 mm lugs are available online, personalizable in length and colour.

Strap replacement requires a simple spring bar removal tool. Position the watch with the strap facing upwards, locate the small cylindrical pin that traverses the lug, insert the tool tip into the lateral aperture of the spring bar and gently push downwards to release the pin. Repeat on the opposite side. To insert the new strap, align the lugs with the holes and push the spring bar until the click-engagement is felt.

The lifespan of a leather strap depends upon frequency of wear, environmental conditions and artisanal quality standards. Straps crafted from first-grade alligator or shell cordovan with vegetable tanning easily last 4–7 years under regular use (three to four days weekly), developing a captivating patina. Calfskin boasts similar longevity but requires routine maintenance. Technical rubber exceeds 5–8 years in hostile environments. Milano Straps guarantees 18 months and offers thread replacement to extend the functional lifespan of your strap.
