Strap for Symphonette XL Diamond / MOP / Bracelet

The Longines Symphonette L2.307.0.87.6 features a lug width of 13mm. This measurement is proportionally calculated to match the 24.90mm case diameter: measure from the inside of one lug to the inside of the opposite lug to verify accuracy. A strap with exactly 13mm width ensures balanced proportions without visual compromise.

For the Symphonette, polished alligator in cognac or deep brown represents the most refined aesthetic choice: the flat grain of crocodile leather accentuates case finesse. Vegetable-tanned calf (pearl grey, burgundy, black) offers versatile refinement. For informal wear, a cotton or silk NATO strap in grey maintains visual proportion relative to the smaller case.

Strap replacement requires a spring bar removal tool: gently depress the spring bar lug connector to release tension. Carefully remove the old strap and align the new one with the lug holes. Ensure the width is precisely 13mm and thickness does not exceed 4.5mm to avoid forcing the lugs. Alternatively, Casati Milano atelier offers professional installation by appointment.

Yes, milanostraps.it produces handcrafted straps compatible with the Symphonette in 13mm width. Materials include alligator, vegetable-tanned calf, shell cordovan, and NATO fabrics. Each strap is customizable in length, colour, initials, and stitching thread type. Artisanal quality ensures visual coherence with the model's vintage heritage.

A quality strap with vegetable tanning typically lasts 3-5 years with daily wear. Exposure to moisture, perspiration, and mechanical wear on the keeper and buckle influence durability. Structured leathers such as alligator age visually with greater grace. Casati Milano warrants 18 months on handcrafted work and recommends preventive replacement every 4-5 years to maintain optimal proportions with the case.
