Strap for Elegant Collection Automatic 39 Stainless Steel / White / Bracelet

The lug width of the Longines Elegant L4.910.4.11.6 is 20 millimetres. This measurement represents the distance between the two attachment pins (lugs) and is essential for selecting compatible straps. To verify correctly, measure the space between the inner edges of the pins: a Longines Elegant requires 20mm straps for precise mounting and error-free fitment.

The ideal strap depends on your usage and dial variant. For pure elegance, dark brown alligator creates harmony with the stainless steel case. If you prefer natural patina and organic ageing, vegetable-tanned calf leather is the recommended choice. A linen NATO is perfect for summer, whilst vulcanised black rubber creates sophisticated contrast. The Casati Milano atelier can guide you through personalised selection.

Changing the strap is straightforward: obtain a small screwdriver. Remove the pins from their respective holes on the case side, gently sliding the old strap upward. Insert the pins of the new strap, aligning them with the holes, pressing until you feel the click. The procedure takes less than five minutes and requires no specialist tools. For professional installation, Casati Milano offers in-atelier service by appointment.

Yes, provided the strap is manufactured for a 20mm lug width. Milano Straps' artisanal straps are specifically engineered for this dimensional standard and fit perfectly without compromise. Avoid straps of different widths (18mm or 22mm), as they would cause play or abnormal pressure on the pins. Dimensional compatibility is the only determining technical criterion.

A quality leather strap (alligator or vegetable-tanned calf) has an average lifespan of 3–5 years if worn daily, extending to 5–8 years if used occasionally. Factors such as perspiration, sun exposure and humidity accelerate wear. Straps handcrafted by Milano Straps include an 18-month warranty and can be serviced or regenerated by the master craftsman at Casati Milano to extend operational life.
