Strap for Endurance Chrono - Orange / leather strap

The lug width of the Limes Endurance U8797-LC2.2 is 20 mm. This intermediate size is not a mainstream commercial standard, but represents the ideal constructive proportion for the 41.20 mm case diameter. Measure correctly by placing a ruler on the inner face of the lug, from spring bar to spring bar. Avoid confusing this measurement with the case diameter or the visual external width of the lug itself.

The pairing depends on usage and personal aesthetics. An alligator with regular grain in black or dark brown emphasises the instrument's nature whilst maintaining formal elegance. Vegetable-tanned calf creates a narrative dialogue with the steel, developing natural patina over time. For dynamic or sporting use, ballistic nylon NATO offers practicality and versatility. Vulcanised rubber amplifies the racing character. Atelier Casati Milano manufactures all these options in 20 mm size with options for deployante or manual buckle.

Strap replacement on 20 mm lugs follows the standard procedure: locate the two spring bars (one on each lug) on the Endurance. Using a spring bar tool, compress the metal ball slightly toward the centre, creating space. Remove the old strap diagonally. Insert the new strap (verifying it is 20 mm) by aligning the holes with the spring bars, then release pressure. Ensure the strap sits perfectly on both sides before wearing. If uncertain, consult a certified watchmaker.

Any strap with exactly 20 mm lug width is mechanically compatible with the U8797-LC2.2. Atelier Casati Milano manufactures a complete collection in this specific size: alligator, calf, shell cordovan, NATO, rubber. All straps are available online under the 20mm strap section of milanostraps.it, with customisation options (colour, finish, buckle type, length). Avoid generic industrial catalogue straps: a 20 mm bespoke strap maintains constructive precision that mass-produced alternatives cannot guarantee.

Lifespan depends on usage intensity, tanning method and environmental conditions. High-quality alligator with vegetable tanning resists 3–5 years of moderate daily wear, developing aesthetic patina that increases narrative value. Vegetable-tanned calf has similar lifespan, with more visible ageing. Ballistic nylon NATO provides 5–7 years of mechanical resistance without obvious aesthetic deterioration. Vulcanised rubber has a lifecycle of 4–6 years before potential wear cracks. To extend lifespan: protect from prolonged moisture exposure, avoid direct heat, perform periodic cleaning. Atelier Casati Milano offers restoration services and component replacement (buckles, stitching) to extend strap life.
