Strap for Symphonette S Stainless Steel / Rose Gold / Diamond

The lug width of the Longines Symphonette L2.305.5.87.7 is 9 millimetres, a non-standard measurement requiring specific straps. To verify compatibility, measure the distance between the two case lugs: it must be exactly 9 mm. This specification is critical to avoid misalignment and mechanical stress on the lugs.

For the Symphonette L2.305.5.87.7, we recommend alligator straps in dark brown or tortora grey, which enhance the rose gold and stainless steel case. Alligator leather offers regular grain and natural texture that amplifies discreet luxury perception. Alternative options include vegetable-tanned calf or black shell cordovan for those seeking constructive versatility.

To change the strap, remove the two spring bars holding it to the case using a spring bar tool. Extract the previous strap and insert the new one, ensuring the bars seat properly in the lug holes. Verify visual alignment before wearing. For professional assistance, the Casati Milano atelier performs strap changes by appointment.

Yes, quality aftermarket straps are fully compatible with the Symphonette L2.305.5.87.7, provided they respect the 9-millimetre lug width. On milanostraps.it you'll find customisable leather straps (alligator, calf, shell cordovan) and technical materials, with length adjustment options and choice of thread colour.

A quality leather strap typically lasts 3-5 years of regular wear, depending on tanning method (vegetable-tanned leather develops more gracefully) and usage habits. Vegetable-tanned leather develops natural patina that improves aesthetics over time. The Casati Milano atelier provides 18 months warranty on straps and allows maintenance and replacement of attachment components.
