Strap for Equestrian 23.5 Arabic

The Longines Equestrian L6.129.4.73.2 features a lug width of 10mm. This is a reduced dimension, consistent with the 23.50mm female case diameter. To verify, measure the distance between the inner edges of the two side lugs perpendicularly to the spring bars.

For the L6.129.4.73.2, we recommend an alligator strap in cognac or deep burgundy, or a pressed calf leather that develops patina over time. Both materials preserve the refined elegance of the mother-of-pearl dial without competing with it. Avoid heavy materials such as rubber, which would appear disproportionate to the case's compact dimensions.

To change the strap, gently lift the case and push the spring bars outward from the lug attachments. Once loosened, extract each bar with a small lever or dedicated tool to avoid scratches. Repeat on the opposite side, then insert the new strap by positioning the bars in their seats and ensuring they sit firmly in place.

Any strap featuring a 10mm lug width is compatible with the L6.129.4.73.2. The aftermarket offers broad selections in alligator, calf, canvas and rubber; however, we recommend solutions crafted by specialised artisans who guarantee precise tolerances on attachments, avoiding movement or damage to the mounting mechanism.

Leather strap durability depends on frequency of wear and humidity conditions. A quality alligator or calf strap, worn daily, maintains structural integrity for 3–5 years before replacement is required. Exposure to perspiration, rain and UV light accelerates degradation. More carefully stored straps may last 7–8 years. Artisanal warranties such as Casati Milano's cover 18 months.
