Strap for Symphonette L MOP / Bracelet

The lug width (distance between lugs) of the Longines Symphonette L2.306.4.87.6 is 11mm. This measurement represents the space between the case attachments where the spring bars and strap lugs engage. To verify it precisely, use a digital calliper to measure the internal distance between the two mounting points on the case. The 11mm width is proportioned to the compact case diameter (21.90mm) and ensures compatibility with straps of the correct specification.

Alligator leather is the most natural choice for the Symphonette: the natural grain pattern harmonises elegantly with the case's geometric proportions. A secondary option is vegetable-tanned calf leather, which ages gracefully and develops authentic patina. For greater versatility, a robust canvas NATO strap or FKM rubber strap offers practicality without compromising the watch's refined character. Avoid synthetic materials: the Symphonette deserves natural leather or quality textiles.

The strap is changed using a spring bar removal tool. Position the watch on a stable, flat surface. Insert the tool's flat tip into the hole on the side of the strap lug, compress gently to relieve tension on the spring, then withdraw the pin. Repeat on the opposite side. Install the new strap by reversing the procedure. If you lack experience, consult a professional watchmaker: the Symphonette deserves expert hands during this operation.

Yes, any strap with an 11mm lug width is compatible with the Symphonette L2.306.4.87.6. On milanostraps.it you will find artisanal straps in alligator, calf, cordura and rubber, all crafted specifically for this measurement. The leather quality and construction care often exceed factory originals: carefully selected hides, hand-stitching, personalisation with initials and custom thread colours. Always verify that the lug width is exactly 11mm before purchasing.

A quality leather strap (alligator, calf, shell cordovan) typically lasts 5-7 years with daily wear, provided it receives regular maintenance. Longevity depends on factors such as tanning method, intensity of use, exposure to moisture and perspiration, and care applied. Vegetable-tanned leather ages gracefully, developing a character-rich patina. Rubber straps offer greater longevity (8-10 years) but lack the aesthetic nobility of natural leather. The Casati Milano atelier provides an 18-month warranty on all bespoke straps, covering manufacturing defects and abnormal wear.
