Strap for La Grandes Classique Quartz 36 PVD Rose / White Roman / Strap

The lug width of the L4.755.1.91.2 is 20 millimetres. This width is the classic standard for 36mm watches and is fully compatible with all 20mm straps in our catalogue. To verify the measurement, position a ruler between the lug holes: the distance between the inner edges of the metal lugs must be exactly 20mm.

For this classic timepiece, we recommend top-quality alligator in dark colours (ebony or deep brown) as it respects the formal simplicity of the case and creates elegant visual contrast. Alternatively, vegetable-tanned calf develops a fascinating patina over time, whilst shell cordovan offers an almost sculptural hardness and lustre. Your choice depends on intended use: alligator for formal settings, calf for greater versatility, cordovan for distinctive character.

Strap replacement involves removing the pins that connect the lugs to the case. Use a dedicated tool (spring bar tool or small flat screwdriver) to gently extract the pin from the outside of the case, pushing from inside outwards. Once the pin is removed, the lug will detach. Repeat on the opposite lug. To fit the new strap, reinsert the pins in reverse, ensuring they are fully seated in their housings.

Yes, absolutely. The Longines L4.755.1.91.2 uses standard 20mm lugs, so any aftermarket strap of the same width is compatible. We recommend, however, also verifying the thickness of the strap at the lug junction to avoid excessive mechanical play. Milanostraps offers 20mm straps personalised in leather, material and measurement, with warranty and bespoke service available at the Casati Milano atelier.

Leather strap longevity depends on material and wear: premium alligator typically lasts 5-7 years with daily use, whilst cordovan can exceed 10 years. Vegetable-tanned calf usually lasts 3-5 years. Key factors include exposure to moisture, skin perspiration and cleaning frequency. A well-maintained strap, dried regularly and stored in a cool place, retains structural and aesthetic integrity far longer. Milanostraps guarantees 18 months on its products.
