Strap for Elegant Collection Automatic 9 Stainless Steel / Red Gold / White

The lug width of the Longines Elegant L4.910.5.12.7 is 20 millimetres. This measurement is specific to this model and requires purpose-sized straps. To verify the measurement, use a digital calliper positioned between the inner ends of the case lugs. The 20mm straps available at milanostraps.it are selected to guarantee precise ergonomic compatibility with this case.

For the red gold and stainless steel bicolour case, dark brown alligator is ideal: its natural grain structure enhances metallic surfaces and creates visual contrast. Vegetable-tanned calf leather, particularly in cognac or whisky tones, offers timeless elegance and develops a patina that improves with time. Cordovan in burgundy creates unparalleled natural lustre. Vulcanised rubber is suitable for daily wear and practical applications.

The procedure requires a spring bar tool (specialist instrument for removing pins). Position the tool beneath one of the pins, apply gentle upward pressure to compress the internal spring, and slide the pin out of its seat. Repeat for the second pin. Install the new strap by reversing the procedure, ensuring both pins are fully inserted into the case seats. Professional assistance from a watchmaker or Casati Milano atelier is recommended for precision.

Yes, provided the lug width is precisely 20 millimetres. All quality aftermarket straps at 20mm are compatible with the L4.910.5.12.7 model. milanostraps.it supplies handcrafted 20mm straps specifically dimensioned for this case, with customisation options (sizing, initials, stitching thread type). Casati Milano atelier also offers bespoke creation with material consultation.

Durability depends on usage intensity, climatic conditions, and material quality. A well-maintained natural leather strap (alligator, calf, cordovan) typically lasts 3-5 years with regular wear. Prolonged exposure to humidity, intense heat, or direct sunlight reduces longevity. Vegetable tanning develops a protective patina over time. milanostraps.it and Casati Milano atelier provide straps with 18-month warranty and specialist maintenance.
