Strap for Legend Diver Date / Mesh

The Longines Legend Diver L3.716.4.50.6 features a 22mm lug width. This measurement represents the distance between the pins connecting the case to the strap and is the optimal standard for a 42mm diver. To verify that a strap is compatible, measure the space between the two lugs: it must be exactly 22mm.

The choice of strap depends on your intended use. For a classically sophisticated aesthetic, alligator with vegetable tanning in honey tone is the most elegant solution. If you seek durability and character, Tuscan calf with vegetable tanning offers natural grip and aged patina. For authentic diving capability, a woven NATO or anti-shock rubber ensures performance in humid and saltwater environments.

The strap is replaced by removing the lateral pins that connect the lugs to the case. Use a spring bar tool or consult a watchmaker to avoid damaging the case. Once the pins are extracted, the old strap detaches; thread the new strap by aligning the lug holes with the pins and reinserting them until they click into place.

Yes, provided the strap is dimensioned for 22mm lugs. Artisanal straps handcrafted in Italy with 22mm lug width are fully compatible and often offer superior construction quality compared to OEM straps, especially when made from alligator or calf with vegetable tanning.

A leather strap's lifespan depends on usage and maintenance. Well-maintained calf with vegetable tanning lasts 3–5 years; alligator can exceed 5 years thanks to its denser structure. Constant exposure to saltwater reduces longevity; anti-shock rubber resists longer in marine environments. Proper care—regular drying and periodic conditioning—significantly extends strap life.
