Strap for Heritage Chronograph 1940 Portugal

The lug width of the Longines Heritage L2.814.4.96.0 is 20mm. This measurement represents the distance between the lugs where the strap is attached, a mid-size standard in sports chronographs that reflects the proportions designed in the 1960s. It is essential to verify this measurement correctly before purchasing an aftermarket strap.

The ideal strap depends on use and personal preferences. A vegetable-tanned alligator strap represents the most authentic pairing, thanks to its characteristic grain that dialogues with the vintage proportions of the case. Shell cordovan, with its natural patina that evolves over time, creates a striking contrast between steel and leather softness. High-grade calf offers versatility, whilst rubber and technical fabric ensure maximum durability.

Strap replacement requires a specific tool to remove the lug pins, available from watchmakers or in dedicated kits. Position the watch on a soft surface, locate the small holes on the side lugs and carefully insert the tool to extract the pin. Once removed, slide the old strap away from the pins. Insert the new strap and reinsert the pin, taking care not to force it to avoid damaging the lugs.

Yes, any strap with a 20mm lug width is compatible with the L2.814.4.96.0. Always verify that the strap has been measured correctly: the lug width must match exactly with the case pins. Straps from different manufacturers, alternative leathers and custom finishes are fully suitable. Milanostraps.it offers a selection of 20mm straps ready for shipping, customizable in size, initials and stitching thread.

The lifespan of a leather strap depends on the type of tanning, construction quality and intensive use. An alligator or shell cordovan strap can last 3–5 years with routine maintenance (regular cleaning, protection from excessive moisture). A high-quality calf strap has a similar lifespan. Natural leather ageing is not a defect but an added value: patina and slight stretching impart character to the watch. The 18-month warranty offered by Casati Milano covers manufacturing defects and guarantees free replacement in case of breakage due to manufacturing faults.
