Strap for Symphonette S Roman

The lug width of the Longines Symphonette L2.304.4.71.0 is 8mm. This dimension is specific to the 16mm case and was purposefully designed by Longines to maintain optical balance and proportion. To verify the lug width, position the watch with its original strap and measure the internal distance between the two lugs: this measurement corresponds precisely to 8mm.

For the Symphonette L2.304.4.71.0, we recommend straps in alligator or fine vegetable-tanned calf leather. Alligator is the most fitting choice, aligned with Longines' luxury heritage, featuring a regular grain that respects the case's proportions. Calf leather is ideal for daily wear and develops a beautiful natural patina over time. For sportier contexts, structured rubber straps maintain balanced proportions without adding visual weight to the timepiece.

Changing the strap is a delicate operation on such a compact timepiece. Remove the original strap by disengaging the spring bars from the lugs—a task requiring a dedicated tool and care to avoid scratching the case. Insert the new strap by threading one end through the lug, positioning the spring bar in its dedicated seat, and repeat for the opposite end. If you lack experience, entrust this task to the Casati Milano atelier for professional handling.

Yes, it is possible to use quality aftermarket straps provided the lug width is precisely 8mm. However, not all 8mm straps maintain the ideal aesthetic proportions on a 16mm case. Milano Straps offers a specialised collection of 8mm-compatible straps, carefully selected for visual harmony with the Symphonette. Before purchasing, verify that the strap respects proportions and is crafted with artisanal quality.

A quality leather strap can last 3 to 5 years with daily wear, depending on the leather type and environmental conditions. Alligator straps tend to have greater longevity due to the leather's natural durability. Vegetable-tanned calf requires more attention to moisture exposure but develops a captivating patina. The warranty offered by Casati Milano for bespoke straps covers 18 months, including manufacturing defects and premature wear.
