Strap for Heritage 1940 White

The Longines Heritage L2.767.4.13.2 features a 20mm lug width. This measurement is taken between the internal pins of the lugs where the strap attaches. It is crucial not to confuse lug width with case diameter (38.50mm): precise measurement requires a digital calliper positioned perpendicularly to the case.

The ideal strap depends on intended usage. For formal and historical aesthetics, we recommend alligator in solid dark tones (black, dark brown) or shell cordovan, which develops natural patina over time. For daily versatility, vegetable-tanned calf leather in cognac or burgundy tones complements the steel case perfectly. For dynamic contexts, quality technical rubber in black or dark grey maintains aesthetic coherence.

The procedure is straightforward: using a dedicated tool (spring bar remover), gently push inward to release the tension of the elastic pin connecting the strap to the lug. Extract the pin from the case lug. Position the new 20mm strap and reinsert the pin until you hear the characteristic 'click' of engagement. Verify that the pin is fully seated on both sides of the lug.

Yes, all straps with a 20mm lug width are compatible with your watch. milanostraps.it offers a comprehensive selection of artisanal 20mm straps customisable in length, leather type, initials and stitching colour. For an even more exclusive experience, Casati Milano creates bespoke straps with personalised material selection.

Durability depends on leather quality, frequency of use and environmental conditions. A high-quality alligator or shell cordovan strap typically lasts 3-5 years with regular daily use, developing a desirable patina. Vegetable-tanned calf leather lasts 2-4 years. The 18-month warranty offered by Casati Milano covers manufacturing defects, whilst natural leather wear is part of the accessory's aesthetic evolution.
