Longines
1832 L4.827.4.52.0— lug 20mm

The lug width of the Longines 1832 L4.827.4.52.0 is 20mm, measured between the inner spring bar posts of the case. This dimension is essential for selecting a compatible strap: any strap with 20mm lug width fits the case perfectly without lateral play.

The ideal strap combines the watch's discreet sportiness with noble materials: natural alligator for sophistication, smooth calf for minimalism, shell cordovan for durability and rarity, or vegetable-tanned leather for evolving patina. The brushed steel case dialogues beautifully with tanned leather, amplifying its refinement without excess.

The procedure is straightforward: use a spring bar tool to depress the elastic posts holding the old strap. Insert the posts into the holes of the new strap and release. Ensure the posts click correctly into both holes to prevent loss risk. If uncertain, contact Casati Milano atelier for professional assistance.

A high-quality artisanal leather strap, with vegetable tanning or natural alligator leather, lasts 3-5 years with moderate daily use. Longevity depends on frequency of wear, sun exposure, humidity, and maintenance. Shell cordovan can endure 7-10 years.
