Strap for Equestrian Horseshoe 34 Diamond / Black

The Longines Equestrian L6.138.0.57.0 features a lug width of 16mm. This dimension represents the space between the case lugs where the strap is inserted. To verify compatibility, measure the distance between the two sides of the lug: it must correspond exactly to 16mm. This lug width automatically excludes straps dimensioned for 18mm, 20mm, or 22mm.

For the Longines Equestrian L6.138.0.57.0, we recommend fine-grained noble leathers: American alligator for discreet elegance, vegetable-tanned calf for warm patina development over time, shell cordovan for superior durability and natural lustre. For informal contexts, a 16mm woven NATO strap with steel deployante clasp offers versatility whilst maintaining classical character. Your choice depends on usage: formality requires leather, versatility requires NATO or rubber.

To change the strap: position the watch on a soft protective pad. Use a dedicated spring bar tool to gently lift the tension bar (spring bar) from one side. Remove the bar without dropping it. Extract the old strap. Insert the new strap into the lug and reinserrt the bar into its seat, ensuring it is firmly positioned on both sides. Repeat on the opposite side. Verify the final positioning by ensuring the strap is perfectly aligned.

Yes, any 16mm aftermarket strap is compatible with the Longines Equestrian L6.138.0.57.0. Milano Straps offers a curated selection of 16mm straps ready for shipment, customizable in length, initials and stitching thread.

The lifespan of a leather strap depends on material quality, frequency of use and environmental wear. Standard calf: 2–3 years with daily wear. Premium leathers (alligator, cordovan): 4–6 years with proper maintenance. Vegetable-tanned leather develops patina but resists longer if exposed to moderate humidity. Leathers in very humid or intense sunlight environments age more rapidly. Milano Straps guarantees 18 months on bespoke straps. Regular maintenance (cleaning, hydro-repellent treatments) significantly extends useful life.
