Strap for Equestrian 23.5 Diamond / Roman

The lug width of the Longines Equestrian L6.129.0.71.2 is 10mm. This non-standard measurement requires purpose-designed straps and careful measurement: position a digital calliper perpendicularly between the inner lug shoulders, excluding protruding case material. An undersized strap will leave unsightly gaps, whilst an oversized strap simply will not fit.

Genuine alligator leather of superior quality is the ideal choice to emphasise the formal and elegant character of this timepiece. Vegetable-tanned leather offers visible aging over time, becoming progressively more refined. For greater versatility, structured rubber-treated calf ensures resistance to external elements. NATO straps and natural rubber introduce a contemporary-sporty note without sacrificing sophistication, creating light and functional visual contrast.

The Longines Equestrian L6.129.0.71.2 features standard spring bar lugs. To replace the strap: use a dedicated tool (spring bar tool) to compress the internal spring; extract it completely; align the new strap holes with the lug and release the spring bar to secure. Proceed with care to avoid scratching the case. If uncertain, entrust the task to a specialised service centre.

A quality leather strap – alligator, calf or vegetable-tanned – typically lasts 3–5 years with daily use and ordinary maintenance (gentle cleaning, limited exposure to extreme humidity, rotation with other straps). Vegetable-tanned leather tends to age elegantly, developing a noble patina. Alligator, being more durable, can exceed 5 years whilst maintaining structural integrity. Rubber straps offer greater longevity (6–8 years) owing to resistance to environmental factors, though the material progressively loses elasticity.
