Strap for Symphonette S MOP

The lug width of the Longines Symphonette L2.304.4.87.0 is 8mm. This measurement represents the vertical thickness of the space between the lugs where the strap seats. To verify it precisely, insert a calliper or ruler into the cavity between the lugs: you will obtain the exact value. It is important to check directly on the watch, as manufacturing tolerances can vary slightly between different production batches.

For such a refined and miniaturised timepiece, we recommend structured alligator (in dark brown or black colourways) as the premium choice, for its natural grain and extraordinary softness. An excellent alternative is vegetable-tanned calf leather, which develops an aristocratic patina over time. A silk NATO or vulcanised rubber strap remain functional options for casual daily wear. Avoid varnished leathers or plastic finishes: they would betray the watch's constructive philosophy.

The strap is changed by extracting the spring bars that hold it fixed to the lugs. Using an appropriate tool (or a small flat blade), push the pin from the opposite side until it is completely freed. Remove the old strap, then seat the new strap on the pins and reinsert them into the lugs. Ensure the strap is firmly seated before wearing the watch. For flawless work, Casati Milano offers the strap-change service by appointment.

Yes, the model is compatible with quality artisanal aftermarket straps, provided they respect the 8mm lug width. MilanoStraps offers a selection of ready-to-ship straps customisable in measurements, initials and stitching thread colour. For a bespoke experience, the Casati Milano atelier creates custom straps with personal choice of leather and 18-month warranty. Always ensure that the strap is manufactured to precise technical specifications.

A quality leather strap, crafted with vegetable tanning, has an average lifespan of 3–5 years of regular daily wear. Longevity depends on factors such as moisture exposure, frequency of wear and maintenance. An alligator or shell cordovan strap tends to last slightly longer thanks to the natural characteristics of the leather. MilanoStraps/Casati Milano's standard warranty is 18 months. To extend useful life, avoid prolonged water immersion and occasionally apply a balm for natural leathers.
