Strap for Equestrian Horseshoe 34 Black

The lug width of the Longines Equestrian L6.138.4.57.0 is 16 millimetres. This specific measurement is determined by the internal distance between the two lugs (spring bar holes) protruding from the case. To verify correct compatibility, use a digital calliper or ruler to measure the distance between the pins, ensuring it matches exactly 16mm.

For the Longines Equestrian, we recommend straps in genuine alligator or vegetable-tanned calf leather, which reflect the watch's sophisticated aesthetic. Alligator offers natural texture and tangible luxury feel, whilst vegetable-tanned anilina calf develops a golden patina over time. For sporty use, a natural rubber strap ensures practicality and durability. Recommended colours: cognac, dark brown, polished black.

To change the strap, you must remove the spring bars (pins) connecting the strap to the case. Use a spring bar tool to compress the internal spring and slide the pin out from the lug. Once the old strap is removed, insert the new one by aligning the holes and ensuring the spring bars are fully locked in place. If you lack specialised tools, consult a professional watchmaker.

High-quality aftermarket straps, such as Italian bespoke-made options, offer superior colour and material selection compared to OEM Longines straps. Artisan straps in alligator, shell cordovan, or vegetable-tanned calf provide full customisation (sizing, initials, thread colour) and often equal or superior construction quality. Warranty and after-sales service are elements that distinguish excellence manufacturers.

Strap longevity depends on material and usage. A premium-quality alligator strap lasts 4-5 years with moderate daily wear. A shell cordovan strap, thanks to its extraordinary natural hardness, can exceed 5-7 years. A vegetable-tanned anilina calf strap has an average lifespan of 3-4 years before the leather shows significant wear signs. Periodic maintenance (gentle cleaning and conditioning) substantially extends strap life.
