Strap for La Grande Classique 38 Stainless Steel / Black - Roman / Bracelet

The Longines La Grande Classique L4.866.4.51.6 features 20mm lugs. This width is the historical standard for rectangular dress watches in the Longines portfolio and is perfectly proportioned to the 68mm case diameter.

For this model, we recommend vegetable-tanned leather straps—alligator for maximum elegance, calfskin for daily versatility. Dark brown or classic black alligator creates eloquent neutrality against the stainless steel case. For contemporary register, synthetic rubber with titanium deployante offers comfort and refinement.

Remove the strap by extracting the spring bar connecting it to the lugs. Insert a thin tool (strap removal lever or pen) into the small hole on the spring bar, compress the spring, and slide the strap free. The procedure is identical for installing a new strap. The required lug width is 20mm.

Any strap with a 20mm lug width is compatible with the Longines La Grande Classique L4.866.4.51.6. Online you will find artisanal straps ready for shipment in alligator, calfskin, rubber, and quality synthetic materials, customisable for length and stitch colour.

A quality artisanal leather strap (alligator, vegetable-tanned calfskin) typically lasts 3–5 years with daily use, with variations due to climate, humidity, and usage frequency. Synthetic rubber lasts 5–7 years. Quality construction (double reinforcement, nylon stitching) extends lifespan. Casati Milano offers an 18-month warranty on all custom straps.
