Strap for Column-Wheel Chronograph

The lug width of the Longines Heritage L2.750.8.76.2 is 20mm. This is the space between the two lugs where the strap attaches. To verify it, use a ruler or digital calliper between the two spring bars. Correct measurement ensures full compatibility with aftermarket straps.

For this rose gold chronograph, we recommend vegetable-tanned leather (cognac brown or dark taupe vitello) or black alligator for formal occasions. Shell cordovan is the ideal compromise: robust leather, patina evolves over time, superior wear resistance. For sporty use, vulcanised rubber or brown textile NATO maintains heritage character.

The strap attaches via two retractable pins on the lugs. Using a spring bar tool or thin needle, gently slide the pins out of their seats. Insert the new strap by aligning the holes with the pins, then reposition the pins into the lug holes. Verify that tension is uniform on both sides.

Yes, absolutely. Any strap with a 20mm lug width is compatible with this model. Artisanal quality straps offer superior aesthetic alternatives to original bracelets, allowing personalisation in leather, colour, style (classic, sporty, formal) and details such as initials or stitching thread.

A vegetable-tanned leather strap lasts 3-5 years with daily use, thanks to patina protection. Shell cordovan resists 5-7 years, alligator 6-8 years. Durability depends on environmental humidity, cleaning frequency and use. A vulcanised rubber strap lasts 4-6 years. Casati Milano warranty on bespoke straps is 18 months.
