Strap for Equestrian 23.5 Diamond / Black

The lug width of the Longines Equestrian L6.129.0.57.0 is precisely 10 mm. This measurement, taken between the inner lugs of the case, determines the exact width of compatible straps. You can verify this specification using a digital calliper, positioning it perpendicularly between the two lateral attachment points of the case.

We recommend an alligator strap with vegetable tanning for the Longines Equestrian L6.129.0.57.0 to enhance its equestrian heritage. Vegetable-tanned alligator develops a noble patina over time, acquiring depth in colour. Alternatively, vegetable-tanned calf leather offers softness and versatility, whilst shell cordovan provides exceptional brilliance and durability for daily wear.

To replace the strap, use a dedicated tool (strap or spring bar tool) to gently push the case bars and release the old strap. Proceed with extreme caution to avoid scratching the stainless steel case. After removal, insert the new 10 mm strap by aligning the lateral attachments, then reposition the bars ensuring they click fully into place. If you lack experience, contact the Casati Milano atelier for professional replacement.

Yes, provided they are certified for the 10 mm lug width. Milano Straps' artisanal straps are specifically engineered for this dimension, guaranteeing flawless mechanical and aesthetic compatibility. Always verify that the strap is crafted from high-quality leather or materials to maintain the value and elegance of your Longines timepiece.

A high-quality, artisanally crafted leather strap typically lasts 3-5 years with daily wear, depending on intensity of use, climate and maintenance. Shell cordovan or vegetable-tanned alligator straps resist longer due to fibre density. Milano Straps offers 18 months warranty on bespoke straps, covering manufacturing defects and ordinary wear within the first year and a half of ownership.
