Strap for La Grande Classique Automatic 36 Stainless Steel / Yellow Gold PVD / Champagne

The lug width of the Longines La Grande Classique L4.898.3.32.7 is 18 millimetres. This measurement is taken from the inside of one lug attachment to the inside of the other. A compatible strap must measure exactly 18mm to fit correctly without gaps or misalignment.

For this watch's classical and formal character, a black or dark brown alligator strap is the reference choice. Italian calf leather with vegetable tanning offers elegance with natural patina development over time. For a versatile approach, Japanese shell cordovan combines structural rigidity with warm tones. For casual wear, an anthracite grey or navy blue NATO maintains dignity without excessive formality.

The strap is fastened via the case lugs using spring bars. To remove it: position the watch on a stable surface, locate the small grooves on the lugs, insert a spring bar tool into the groove, press inward to release the spring, and slide the strap downward. Repeat on the other side. To install a new strap, align the new strap's holes with the spring bars, insert the bar into the opposite groove, and press until you feel the engagement click.

Yes, absolutely. All straps with 18mm lug width are compatible. It is essential to verify the exact measurement (inside-inside) before purchase. Leather, NATO, rubber and technical fabric straps measuring 18mm will fit correctly. We recommend selecting leather thickness and rigidity consistent with the watch's style to maintain visual harmony.

A quality leather strap, worn regularly (4-5 days per week), typically lasts 2-3 years. Longevity depends on tanning quality, leather type (alligator lasts longer than common calf), humidity exposure, and frequency of use. Vegetable-tanned leathers develop natural patina and may last longer if properly cared for. Experienced artisans offer buckle replacement or partial repair services to extend strap life.
