Strap for Endurance Neptun2 - steel bracelet

The lug width of the Limes Endurance U8777B-LA3.1 is 22mm. This measurement represents the standard lug width for this model and corresponds to the distance between the two lugs protruding from the sides of the case. It is essential to verify this measurement before purchasing an aftermarket strap to ensure mechanical and aesthetic compatibility.

The choice of strap depends on intended use and aesthetic preferences. For formal contexts, we recommend an alligator or vegetable-tanned calf leather strap, which combine elegance with evolving patina over time. For sports applications or humid environments, a NATO Premium or rubber strap guarantees functional reliability without compromise. All these materials are available in the 22mm size on MilanoStraps.

To change the strap, use a spring bar tool to extract the horizontal pins from the case lugs. Position the tool in the appropriate slot of the pin and apply gentle lateral pressure to compress the internal spring, then extract the pin. Repeat the operation for the other side. Insert the pins into the new strap following the reverse procedure, ensuring that the pin is completely seated and clicks into position.

Yes, the Limes Endurance U8777B-LA3.1 is fully compatible with standard 22mm aftermarket straps available on the market. This lug width is an industry standardisation, giving you access to an extensive catalogue of materials—leather, NATO, rubber—from certified suppliers. MilanoStraps maintains a carefully curated inventory of 22mm straps specifically selected for compatibility and construction quality.

The lifespan of a leather strap depends on intensity of use and tanning quality. An alligator or vegetable-tanned calf strap, used daily under normal conditions, maintains structural integrity for 3-5 years before requiring replacement. Vegetable tanning allows the strap to acquire patina and character over time, whilst minimal maintenance gestures—drying after moisture exposure, occasional application of leather balm—significantly extend the strap's longevity.
