Strap for Elegant Collection Automatic 29 Stainless Steel / White / Strap

The lug width (strap width) of the Longines Elegant L4.310.4.11.2 is 20mm. This width was specifically designed for the 29mm case proportions and represents the ideal compromise between stability and comfort on standard-sized feminine wrists. To verify the measurement, measure the internal distance between the two lugs protruding from the case using a digital calliper.

The choice depends on your lifestyle and usage context. An alligator strap with vegetable tanning offers discreet elegance and evolving patina over time. Shell cordovan represents the pinnacle of luxury and practicality, with tones evolving towards deep burgundy. Hammer-finished calf leather with piano finish amplifies personality. For active daily use, ballistic nato in contrasting colours preserves elegance whilst maintaining extreme practicality.

Strap replacement is performed using a spring bar removal tool. Identify the two horizontal metal pins securing the strap to the case. Insert the spring bar remover into the slot beneath each pin, exerting light vertical pressure to release it. Once both pins are free, the old strap detaches easily. Insert the new strap's pins into the case lugs and push until you hear a click. If uncertain, consult a professional watchmaker.

Yes, all straps marked for 20mm lug width are compatible with the Longines Elegant L4.310.4.11.2. Online you will find a wide selection of artisanal straps in fine leathers, nato, and technical rubber. Always verify that the strap is explicitly marked for 20mm width and that the lug attachment system is standard (universal spring bar).

Leather strap longevity depends on leather quality, frequency of wear and environmental conditions. An artisanal alligator or shell cordovan strap, worn daily, typically lasts 3-5 years before replacement. Quality calf leather resists 2-3 years. Ballistic nato lasts 5-7 years due to fibre durability. The patina developing on leather is not deterioration but aesthetic evolution. Casati Milano guarantees 18 months on all bespoke straps.
