Strap for Military 1938

The lug width of the Longines Heritage L2.788.4.53.0 is 20 millimetres. This measurement corresponds to the distance between the lugs on the watch case where the strap attaches. It is important not to confuse lug width with the case diameter (40 mm). When selecting an aftermarket strap, ensure it is specifically designated for 20 mm.

For the Longines Heritage L2.788.4.53.0, we recommend an alligator strap in dark brown or black, which enhances the elegance of the stainless steel case and white dial. Alligator offers distinctive grain and natural suppleness that highlights the vintage-inspired design. Alternatively, shell cordovan is ideal for those seeking an aristocratic leather that develops character over time. For more sporty contexts, a NATO canvas strap provides practicality whilst remaining coherent with the watch's style.

The strap on the Longines Heritage L2.788.4.53.0 is secured via spring bars located on the case lugs. To remove the strap: 1) use a dedicated spring bar tool or small flathead screwdriver; 2) gently press the pin from one side to disengage it from the lug; 3) extract the old strap. To install a new strap: align the upper spring bar, insert the pin into the first lug hole, then press the opposite end until the second pin clicks into position. Verify that both pins are fully seated.

The lifespan of a leather strap depends on leather quality and daily wear intensity. An artisanal alligator or shell cordovan strap can last 3–5 years with regular use, developing a refined patina over time. Vegetable-tanned calf tends to firm slightly, extending lifespan to 4–6 years. To extend strap life: avoid prolonged exposure to moisture and direct sunlight, store in a dry environment, occasionally apply leather balm (on smooth leathers only). The Casati Milano atelier provides an 18-month guarantee on artisanal straps, covering manufacturing defects and premature wear.
