Frequently asked questions

What is the lug width of the Longines La Grande Classique L4.205.2.11.7?

The lug width of the Longines La Grande Classique L4.205.2.11.7 is 16 mm. This measurement is taken between the two lugs (case horns). This specific dimension determines aftermarket strap compatibility.

Which strap is recommended for the Longines La Grande Classique L4.205.2.11.7?

For this minimalist and refined timepiece, we recommend alligator leather in dark tones (black or brown), vegetable-tanned calf, or shell cordovan. These materials respect the delicate proportions of the 22.20 mm case and the Art Deco quadrant design. Alternatively, a technical NATO strap offers a more casual interpretation.

How do you change the strap on a Longines La Grande Classique L4.205.2.11.7?

Strap replacement requires a spring bar tool. The pins connecting the strap to the case must be extracted carefully from bottom to top. It is advisable to have this operation performed by a professional to avoid damage to the stainless steel case. Casati Milano also provides this service with warranty.

Is an aftermarket strap compatible with the Longines La Grande Classique L4.205.2.11.7?

Yes, provided the lug width is exactly 16 mm. milanostraps.it supplies compatible aftermarket straps made with premium leather and fully customisable. It is important to verify that the spring bar pins are the correct length to prevent instability.

How long does a leather strap last on the Longines La Grande Classique L4.205.2.11.7?

Durability depends on material and usage. Alligator or shell cordovan typically lasts 4-6 years with daily wear; vegetable-tanned calf has similar longevity but develops a fascinating patina. Casati Milano guarantees custom straps for 18 months. Wear is natural and adds character to the accessory.
