Strap for X-Heroes

The lug width of the Elka X-heroes is 20 mm. This unconventional dimension, eccentric compared to industrial standards, requires purpose-designed straps. To verify compatibility, measure the distance between the spring bars protruding from the case: a 20 mm strap fits seamlessly within this space without forcing or play.

The ideal strap depends on usage and aesthetic preference. For formal contexts, we recommend alligator leather in vegetable tannage with cognac tones: the regular grain contrasts elegantly with the polished case flanks. For a functionalist aesthetic, a Cordura NATO in grey or industrial blue radicalises the model's anticonformist identity. FKM rubber offers sport-utility versatility whilst maintaining constructive coherence.

The strap is mounted by inserting the spring bars protruding from the case into the lug slots of the new strap. If the change proves difficult, use a dedicated tool (spring bar tool) to gently spread the bar, easing its seating. Never force the assembly: a 20 mm lug width must accommodate smoothly with no lateral play.

Yes, provided your timepiece features a 20 mm lug width. Before purchase, verify the spring bar diameter of your case. A 20 mm strap is incompatible with watches mounting 18 mm, 22 mm, or other dimensions. Dimensional precision is fundamental to avoiding case damage.

Leather strap durability depends on usage and tannage method. A vegetable-tanned strap typically lasts 3–5 years with daily wear, developing a patina that enriches its aesthetic character. Alligator, more resistant to flexion stress, can exceed 5 years. Perspiration, sun exposure, and humidity accelerate ageing. Periodic maintenance—gentle cleaning and protective treatments—extends service life.
