Frequently asked questions

What is the lug width of the Longines La Grande Classique L4.512.4.58.2?

The Longines La Grande Classique L4.512.4.58.2 features a 16mm lug width. This dimension is proportioned to the 29mm case diameter and should be verified by measuring the distance between the two spring bars on the case.

Which strap is recommended for the Longines L4.512.4.58.2?

For the dress-centric profile of this timepiece, African alligator with fine grain is the optimal choice. Alternatively, vegetable-tanned calf leather or Japanese shell cordovan both guarantee elegance and evolving patina over time.

How do I change the strap on the Longines L4.512.4.58.2?

To change the strap, obtain a spring bar removal tool (small flat-head screwdriver). Gently press the spring bar inward toward the case and extract the metal bar, then repeat on the other side. Insert the new spring bars through the strap holes and reposition the case.

Are there aftermarket straps compatible with the Longines L4.512.4.58.2?
