Strap for Symphonette M Arabic MOP / Bracelet

The lug width of the Longines Symphonette L2.305.4.83.6 is 9mm. This measurement is specific to the model and calculated proportionally to the 18.90mm case diameter. To verify it correctly, measure with a digital calliper the internal distance between the two fixing lugs, positioning the instrument perpendicular to the case.

For the Longines Symphonette L2.305.4.83.6, alligator represents the most balanced choice: the natural grain offers visual depth without optically weighing down the slender case. Alternatively, vegetable-tanned calf leather allows a patina that evolves over time, whilst shell cordovan constitutes the absolute pinnacle for those desiring a strap that develops enduring chromatic richness.

To change the strap on a Longines with 9mm lugs, use a dedicated spring bar tool to compress the lug springs, then gently remove the old strap from the fixing lugs. Insert the new spring bars into the aftermarket strap holes, aligning the 9mm width perfectly, then slowly release the lugs into the case seats. Verify that the strap is perfectly centred before wearing the watch.

All artisan straps constructed with a 9mm lug width are compatible. This includes straps in alligator, calf, shell cordovan, full-grain vegetable-tanned leather, synthetic rubber and, in some cases, quality NATO straps. Straps must be constructed specifically for this width to ensure perfect fit without mechanical stress on the lugs.

A high-quality artisan leather strap, made from premium alligator or calf, lasts on average 3-5 years of daily use, evolving aesthetically over time. Longevity depends on intensity of use, humidity exposure and maintenance. Shell cordovan straps tend to last longer thanks to the natural resistance of the leather. An 18-month artisan guarantee covers construction defects and ensures the quality of stitching.
