Strap for Symphonette L Diamond / MOP / Bracelet

The lug width of the Longines Symphonette L2.306.0.87.6 is 11mm. This measurement is standard for numerous Longines ladies' models and ensures broad compatibility with contemporary artisanal straps. To verify the measurement, position a ruler perpendicular to the top face of the lug and measure from wall to wall of the metal passant.

The most appropriate strap for the Symphonette is alligator leather of quality grade, preferably in black or dark brown patinated finish. Alligator respects the historical proportions of the case and develops natural patina over time. Noble alternatives include vegetable-tanned calf leather or shell cordovan. Rubber or NATO straps are inadvisable, as they compromise the discrete elegance of the model.

Strap replacement requires detaching the lugs from the case. Use a dedicated tool (spring bar tool) to compress the internal clasp of the lug, then gently extract the metal pin. Position the new strap by aligning the holes with the lugs, reinsert the pin and allow the clasp to re-engage. The operation is reversible and requires no specialist skills.

Any strap with 11mm lug width is compatible with the Symphonette L2.306.0.87.6. Select artisanal straps of quality in alligator, calf leather or shell cordovan. Always verify that the strap is long enough to wrap the wrist (minimum 20cm total). Milano Straps ready-to-ship straps offer personalisation in sizes, colours and details.

A high-quality leather strap (alligator, calf, shell cordovan) with vegetable tanning lasts approximately 5-8 years with regular use and ordinary maintenance. Durability depends on intensity of use, sun exposure and humidity. Quality leather develops natural patina that improves aesthetics over time. Artisanal straps from Casati Milano carry an 18-month guarantee from the date of purchase.
