Longines
Heritage L46936782— lug 18mm

The lug width of the Longines Heritage L46936782 is 18mm (internal width). Measure from the inner side of one lug to the inner side of the opposite lug, excluding the case shoulders. This rare 18mm specification reflects the correct proportions for a 35.50mm case diameter, standard among Swiss watchmakers of the 1950s era.

For the L46936782 in pink gold, we recommend honey-toned alligator (premium option with evolving patina), vegetable-tanned calf leather in cognac tonality (sophisticated colour matching), or grey-pearl leather NATO for a modern aesthetic. Your choice depends on intended use: formal, daily wear, or sport-elegance.

Strap replacement requires a spring bar removal tool, widely available online. Insert the flat tip into the groove of the spring mechanism, press inward to release the tension, and extract the bar. Repeat on the other side. Position the new spring bar within the strap, slide it under the lug, and compress both springs into their seats. Alternatively, Casati Milano handles custom replacement with warranty.

No, the 18mm lug width is specific to the L46936782 and very few other vintage or specialist models. Most contemporary watches use 20mm or 22mm. Always verify your case's lug width before purchasing an aftermarket strap.

A quality leather strap (alligator or vegetable-tanned calf) lasts 3–5 years with daily wear, extending to 7–10 years with occasional use. Longevity depends on humidity exposure, UV exposure, and fibre wear. Casati Milano provides 18 months warranty on craftsmanship.
