Strap for Lindbergh's Atlantic Voyage Watch Black

The lug width of the Longines Heritage L2.730.4.58.0 is precisely 25mm. This measurement is specific to this model and ensures proportionate anchoring to the 47.5mm case diameter. To verify accurate measurement, use a digital calliper positioned perpendicularly between the lug shoulders.

For the Longines Heritage, we recommend alligator for classic elegance and natural patina development over time, or calf leather in vegetable tanning for durability and pronounced tactile texture. Ballistic nylon NATO straps preserve authentic avionic character, whilst structured rubber balances the case's visual weight. Material choice depends on intended use and desired aesthetic profile.

Strap replacement requires a spring bar tool to gently compress the elastic pins at the lugs. Position the tool in one of the strap's terminal holes, apply light pressure to release the pin, then remove the used strap. Insert the new strap by aligning the holes with the pins and verify they engage with a firm click. Perform this operation carefully to avoid damaging the lugs.

Yes, quality aftermarket straps can be used provided they respect the 25mm lug width specification. Always verify that the strap is engineered for this specific width and that materials—leather, rubber, fabric—meet good artisanal quality standards. Straps from milanostraps.it are customisable and guaranteed for 18 months if crafted at Casati Milano atelier.

Leather strap longevity depends on tanning method, daily wear and maintenance. Quality alligator typically lasts 3–5 years with regular use, whilst vegetable-tanned calf can reach 5–7 years. Exposure to perspiration, moisture and direct sunlight accelerates ageing. The 18-month warranty on bespoke Casati Milano straps covers manufacturing defects; natural leather wear is considered normal deterioration.
