Elegant L4.330.4.11.2— lug 14mm

The lug width of the L4.330.4.11.2 is 14 millimetres. This measurement represents the distance between the lugs of the case and is the specific standard for this model. Any compatible strap must respect this exact measurement to ensure correct and secure installation. The width can be verified by directly measuring the space between the side lugs of the case, excluding the thickness of the lugs themselves.

Alligator represents the choice of maximum elegance for this timepiece: the fine and regular grain of the American reptile amplifies the refined character of the stainless steel case. Vegetable-tanned calf leather offers a natural patina that matures over time, acquiring depth and character. For more versatile use, articulated rubber transforms the watch into a tool of functional elegance. Finally, cotton NATO allows for a contemporary reinterpretation of military tradition whilst maintaining aesthetic coherence with the model.

The strap is changed via the side lugs of the case. Using a dedicated tool (spring bar tool) or a simple rounded stick, light pressure is applied to the lug to disengage it from the seats of the old strap. Once released from one side, the strap is extracted. Next, the new strap is inserted by correctly aligning the holes at the ends, the lug is positioned, and uniform pressure is exerted until the click of engagement. This process requires care to avoid damage to the case or lugs.

Yes, a quality aftermarket strap is fully compatible with the L4.330.4.11.2, provided that the lug width is exactly 14 millimetres. Many artisanal straps in leather, rubber or NATO offer superior quality and personalisation compared to original straps. Choosing an artisanal strap also allows the timepiece to be personalised according to personal aesthetic preferences: colour, material, thickness and type of closure (deployante, ardillon buckle, velcro) can be adapted to individual needs.

The lifespan of a leather strap depends on the quality of the material, the type of tanning and the intensity of use. A quality leather strap (alligator, shell cordovan, vegetable-tanned calf) used daily has an average lifespan of 3-5 years before showing significant signs of wear. Vegetable tanning tends to age naturally and pleasantly, developing a patina that increases its character. Chrome tanning, more economical, tends to show more evident cracking over time. To extend durability, it is recommended to avoid prolonged exposure to moisture, to periodically clean the leather with a soft cloth, and to alternate the strap with other options when possible.
