Strap for La Grande Classique Quartz 24 Diamond Bezel

The lug width of the Longines La Grande Classique L4.241.0.80.6 is 13mm. This measurement represents the distance between the two lugs (the spring bars) to which the strap is attached. To verify this width correctly, measure the space between the two lugs without including the length of the lugs themselves, as they do not affect strap compatibility.

The best strap depends on your intended use. For formal occasions, we recommend black or dark brown alligator, which enhances the minimalist elegance of the case. For daily wear, vegetable-tanned calf leather in medium brown or cognac tones offers comfort and authentic patina development. A NATO strap in navy blue or grey provides casual versatility whilst maintaining the watch's sobriety.

To change the strap, obtain a spring bar tool with two flat ends. Position the flat end beneath one of the lugs (spring bars) that secure the strap, pressing slightly upward to release the tension. The lug will retract, allowing you to remove the old strap. Repeat from the other side. To install the new strap, align the holes with the lugs and press downward until they are fully seated. Verify that the strap is secure on both sides.

Yes, you may use quality aftermarket straps provided they have a 13mm lug width. Milano Straps offers artisanal straps compatible with various leathers and finishes. Ensure the new strap is manufactured with precise tolerances and that the lugs are slightly thinner than the interior width to guarantee secure fit without lateral play.

The lifespan of a leather strap depends on frequency of use and tanning quality. A high-quality calf leather strap with vegetable tanning can last 3-5 years with moderate daily wear. Alligator tends to last longer due to greater fibre density. Longevity increases if the strap is removed when not worn and occasionally treated with appropriate conditioner. Milano Straps guarantees 18 months on custom-made straps.
