Strap for Lindbergh's Atlantic Voyage Watch

The lug width of the Longines Heritage L2.730.4.78.0 is 25mm. This dimension is essential to ensure a perfect fit between the strap and the case. To verify it, measure the horizontal distance from the inner edge of one lug to the other using a digital calliper. Using a strap with a different lug width (for example, 24mm) would result in an undesirable gap between the strap and the case, compromising both aesthetics and comfort.

The ideal strap for this model must reflect the robust, aviator-inspired character of the timepiece. Alligator leather in vegetable tanning represents the pinnacle choice: the natural grain and patina that develops over time harmonise perfectly with the historical aesthetic. Alternatively, box calf ensures formal elegance, shell cordovan adds aristocratic lustre, whilst NATO straps in canvas or heavyweight cotton emphasise the military spirit of the watch. The choice depends on intended use: leather for formal settings, NATO for sport and everyday wear.

Strap replacement is accomplished through the lugs (the lateral pins that protrude from the case). Using a dedicated tool (spring bar tool), gently compress the spring beneath the pin and pull the pin towards you to extract the strap. The operation requires precision to avoid scratching the case. If inexperienced, we recommend entrusting the task to a professional watchmaker or the Casati Milano atelier, which also offers bespoke strap customisation.

The lifespan of a leather strap depends on intensive use, humidity exposure, and tanning quality. A high-quality alligator or calf strap, with proper maintenance (periodic cleaning, drying after moisture exposure, hydration with specific balm), maintains integrity and aesthetics for 3-5 years of regular use. Vegetable-tanned leather develops a fascinating patina over time, enhancing aesthetic appeal. Rubber or NATO straps have longer durability (5-7 years), being less susceptible to deterioration. Casati Milano offers an 18-month warranty on its products, ensuring structural reliability.
