Strap for Saint-Imier Chronograph

The lug width of the Longines Saint Imier L2.752.8.72.3 is 20 mm. This measurement refers to the distance between the two spring bars that support the strap. At 20 mm, this is a highly sought-after intermediate size that enables versatile styling from formal to sporty whilst maintaining balanced proportions on the 41 mm rose gold case.

For the L2.752.8.72.3 in rose gold, the ideal strap is dark brown alligator leather (Havana or tobacco tones): the fine texture of the leather complements the subdued grey dial and harmonises naturally with the warmth of rose gold. Alternatively, shell cordovan develops extraordinary patina over time, whilst vegetable-tanned calf leather represents a more robust daily-wear option. Polished steel finishes are not recommended, as they create visual disharmony.

Strap replacement is straightforward: use a spring bar tool to gently push the elastic pins downwards, releasing the old strap from the lugs. Align the new strap pins with the lug slots and release the tool: the pins will reposition automatically. On rose gold watches, handle with care to avoid scratching the case.

Yes, any 20 mm strap is compatible with the L2.752.8.72.3. Quality aftermarket straps (such as premium alligator or shell cordovan) do not damage the watch and allow regular rotation between different styles. We recommend rose gold buckles (with integrated deployant) to maintain chromatic coherence with the case, or brushed steel for discreet contrast.

A quality alligator or calf leather strap typically lasts 3-5 years with moderate daily use, depending on humidity and maintenance. Shell cordovan, being more durable, can exceed 7 years. Vegetable-tanned leather tends to wear more quickly (2-4 years) but develops a fascinating patina. Rotating multiple straps is recommended to extend overall lifespan.
