Strap for Column Wheel Chronograph Record

The lug width of the Longines Heritage L4.754.4.52.4 is 20 millimetres. This measurement is standard across the Heritage family and remains consistent throughout the collection. To verify strap compatibility, measure the space between the lug pins using a digital calliper, positioning it perpendicularly at the narrowest point of the lug.

The optimal strap depends on intended use: cognac alligator with natural patina delivers elegance without compromise and enhances the heritage vocation; vegetable-tanned calf maintains the aviator essence whilst developing authentic 1950s texture; vulcanised rubber or NATO fabrics amplify the technical and operational character. milanostraps.it stocks a curated selection of 20mm straps engineered to precise tolerances, customisable through the Casati Milano atelier.

To replace the strap, employ a spring bar tool to disengage the attachment pins from the case lugs. Gently extract each pin by depressing the internal spring whilst levering with the forked end of the tool. Repeat for the opposing pin. Align the new strap's holes with the lugs and reposition the pins, confirming audible engagement. Should you lack confidence, consult a qualified watchmaker to prevent case scratching.

Vegetable-tanned leather ages gracefully whilst developing character; alligator resists mechanical stress effectively; shell cordovan exceeds five years when kept dry. Periodic replacement is standard in horology and advisable once the strap exhibits structural compromise or aesthetic cracking. Casati Milano supplies straps with an 18-month warranty against manufacturing defects.
