Strap for BelleArti 19 Quartz Stainless Steel Black

The lug width of the Longines Heritage L2.194.4.53.4 is 12 millimetres. This measurement refers to the distance between the metal pins (lugs) that attach the strap to the case. It is a rare specification, typical of small-diameter cases, and requires straps manufactured specifically to this standard.

The ideal strap depends on intended use. For formal elegance, dark brown or black alligator offers maximum sophistication. Vegetable-tanned leather develops natural patina over time. For versatility, navy NATO or quality textiles provide practicality. Shell cordovan produces natural lustre without varnishes, suited to aesthetic minimalism.

To change the strap, use a specialised lug removal tool. Place the watch on a soft surface to prevent case damage. Locate the small holes at the sides of the case, gently insert the tool and push the pin downward until it exits the opposite hole. Repeat for the other pin, insert the new strap and reset the pins. Milano Straps provides detailed guides and support.

Only straps manufactured to 12-millimetre lug width are compatible. Standard 14, 16 or 18 millimetre straps will not fit. Milano Straps offers a complete collection of 12mm straps certified compatible with this model, crafted from premium leather and fully customisable.

Durability varies depending on material and usage. Superior-quality alligator and shell cordovan with vegetable tanning last 5-8 years with regular maintenance and rotation between multiple straps. Calf leather ranges from 3-5 years. Longevity extends by keeping the strap dry, protecting from excessive perspiration and direct sunlight. Milano Straps provides 18-month warranty on all manufactured straps.
