Strap for Symphonette S MOP / Bracelet

The lug width of the Longines Symphonette L2.304.4.87.6 is exactly 8 millimetres. This measurement determines the maximum width of any compatible watch strap: no modification is required if the strap is engineered for this specific dimension. Accurate measurement is performed by placing a digital calliper perpendicular to the lugs of the case.

Alligator represents the noblest choice for this model, given its natural texture that dialogues with the guillochéd dial. Vegetable-tanned calf leather offers daily versatility and a patina that evolves over time. For those seeking functional versatility, cotton or silk NATO straps permit a complete aesthetic transformation. Shell cordovan is the choice for those who value exceptional tactile quality and the capacity of the material to narrate personal history through ageing.

Strap replacement is accomplished by disengaging the pins that traverse the lug holes on either side of the case. Position the watch on a stable surface, employ a dedicated strap removal tool or small lever, then gently push the pin from one side. Once the pin is removed, the old strap separates from the case. Installation of the replacement strap follows the reverse procedure: insert the pin through the lug and the keeper ring of the new strap, then secure it firmly. For precision operations, Casati Milano offers strap change service at the atelier by appointment.

Yes, any strap engineered for 8mm lug width is mechanically compatible with the Longines Symphonette L2.304.4.87.6, provided it respects this dimension rigorously. Milano Straps curates a comprehensive collection of 8mm straps in diverse materials—alligator, calf, NATO, rubber—all ready for use and customisable in length, initials and thread colour. Artisanal quality ensures precise finishing and mechanical compatibility.

Leather strap longevity depends upon material quality, tanning method and frequency of use. A strap in alligator or shell cordovan, with vegetable tanning and artisanal construction, may endure 5–10 years with regular maintenance (drying after humidity exposure, occasional conditioning). Vegetable-tanned calf leather exhibits comparable durability. Rubber straps have longer lifecycle windows (10–15 years) but suffer from chemical ageing. Casati Milano furnishes an 18-month warranty on all bespoke straps, covering construction defects and material imperfections.
