Strap for 1832 Moonphase 40 Stainless Steel / Black

The lug width of the Longines 1832 L4.826.4.52.0 is 20 millimetres. It is measured as the distance between the lateral metal lugs of the case where the strap attaches. It does not correspond to the case diameter (40mm), but represents the specific attachment space. Any aftermarket strap must strictly respect this measurement to ensure correct fit without lateral play.

For the Longines 1832 L4.826.4.52.0, an alligator strap with tight grain is recommended to enhance the severity of the blue dial, or vegetable-tanned calfskin that develops cognac patina over time. For sporty use, a Cordura NATO maintains formal rigour with practical quick-change capability. Shell cordovan in burgundy represents the maximum durability option, lasting over three years of daily wear with evolved patina.

Strap replacement requires extraction of the two transverse pins (spring bars) located at the ends of the lugs. Use a dedicated tool (pin remover) to compress the pin's internal mechanism and slide out the old strap. Insert the new strap in the same position, secure the pin until the click. Do not force: a crisp click indicates correct positioning. If inexperienced, Casati Milano offers professional change with lug-case alignment verification.

Yes, provided the strap is sized for the 20mm lug width. Milanostraps.it offers artisanal compatible straps, customisable in length, initials, and thread thickness. Compatibility is guaranteed by correct lug width; construction quality, leather selection, and finishes must nevertheless meet artisanal standards to enhance the integrity of the Longines model.

Duration depends on material and daily use. Vegetable-tanned calfskin lasts 18-24 months with regular maintenance (sweat hygiene, controlled sun exposure); alligator lasts 24-36 months; shell cordovan exceeds 36 months of daily wear. All Casati Milano straps include an 18-month warranty against construction defects. Maintenance consists of periodic cleaning with a soft cloth and application of specific balm every 6-8 months.
