Strap for La Grande Classique Automatic 36 Stainless Steel / Black - Roman

The Longines La Grande Classique L4.908.4.51.2 features a lug width of 20mm, measured between the two attachment pins on the case. This dimension is standard for mid-sized watches (36mm diameter) and is compatible with the extensive range of 20mm straps available in the market.

Given the formal and classical character of this model, an alligator or shell cordovan leather strap represents the most appropriate choice. Alligator leather offers a regular, lustrous texture ideal for formal occasions; shell cordovan presents a deep patina that ages gracefully. For everyday versatility, a smooth calfskin in black or brown ensures elegance without compromise.

The Longines La Grande Classique is fitted with standard spring bars. Using a dedicated strap-changing tool or a small screwdriver, gently press inward on one of the two springs to release one end of the strap, then extract it from the case lug. Repeat on the other side. Insertion of the new strap occurs in reverse, ensuring both springs are properly positioned.

Yes, any strap with a 20mm lug width is compatible with this model. The artisanal straps from milanostraps.it are manufactured to the same technical specifications and can be personalised in length, finish and details. The important thing is to verify that the attachment pins correspond to 20mm and that the strap construction respects the case thickness.

A high-quality, vegetable-tanned natural leather strap typically lasts 3-5 years with moderate use (4-5 days per week). Longevity depends on ambient humidity, frequency of use and care: avoiding prolonged direct sunlight exposure and keeping the leather slightly hydrated significantly extends its lifespan. Casati Milano straps include an 18-month warranty and can be regenerated or replaced beyond that period.
