Strap for Equestrian 23.5 Roman

The lug width of the Longines Equestrian L6.129.4.71.2 is 10mm. This unconventional measurement requires straps specifically manufactured to 10mm ±0.2mm tolerance to ensure perfect fit at the case lugs without play or excessive tension.

For the Longines Equestrian L6.129.4.71.2, we recommend fine-grained alligator for conservative elegance, grained calf for natural patina development, or shell cordovan for chromatic evolution over time. A black or dark brown strap maintains the minimalist aesthetic of the timepiece whilst emphasizing its equestrian identity.

To change the strap: position the watch with lugs parallel to the work surface. Use a thin tool (spring bar tool) to apply gentle pressure to the spring mechanism, which releases the bar. Remove the bar, detach the strap, and insert the new one using the reverse procedure. Verify that the lugs fully engage with the bar.

Any strap with 10mm lug width is compatible, regardless of manufacturer, provided it meets precise tolerances. Milanostraps offers 10mm straps in alligator, calf, cordovan and specialty leathers, all customizable in length, colour and finishes.

A premium leather strap, subject to vegetable tanning, typically lasts 3-5 years with daily wear. Longevity depends on exposure to moisture, perspiration and UV rays. Cordovan straps, due to fibre density, may last 6-8 years. Casati Milano guarantees 18 months on custom straps; however, patina improves over time, virtually extending the strap's useful life.
