Strap for Elegant Collection Small Second 34.5 Stainless Steel / Silver - Linen / Bracelet

The Longines Elegant L4.312.4.77.6 features a lug width (also called ansa width) of 18mm. This measurement indicates the distance between the internal lugs on the case, where the watch strap must be fitted. Longines' precision engineering ensures very tight tolerances, so only 18mm straps will fit correctly to this reference.

The ideal strap depends on intended use. To preserve the dress-watch character, a vegetable-tanned alligator leather strap in dark brown or black is the conservative choice. For business contexts, a smooth calf leather strap in black or burgundy reinforces formality. Those seeking versatility may choose a NATO-style cotton-polyester strap. For humid environments, structured rubber is the functional solution. All materials must respect the 18mm lug width.

Strap replacement is accomplished via the case lugs (spring bars). You will need a spring bar tool or fine-pointed implement to depress the small sprung mechanisms that retain the bars. Insert the tool between the lug and current strap, compress the spring, withdraw the bar, and repeat for the replacement strap. When in doubt, consult a professional watchmaker to avoid case damage.

Yes, provided the strap respects the 18mm lug width specification. Bespoke artisan straps, crafted from alligator, calf leather, and rubber, fit perfectly to this model. The quality of an aftermarket strap often exceeds the original equipment, especially if made from vegetable-tanned leather and hand-finished. Always verify the 18mm width before purchase.

A natural leather strap typically lasts 2–4 years under daily wear, depending on climate, frequency of use, and maintenance. Vegetable-tanned leather ages better than mineral-tanned leather, developing an organic patina. Exposure to perspiration, moisture, and sunlight accelerates wear. Proper care—drying after water contact, annual conditioning with natural wax—extends lifespan significantly. MilanoStraps bespoke straps include an 18-month warranty against manufacturing defects.
