Strap for Symphonette S Diamond / Roman

The lug width of the Longines Symphonette L2.304.0.71.0 is 8mm. This measurement, also known as anse width, represents the distance between the front and rear lug pins of the case. At 8mm, this is a non-standard size that requires specific straps—it is not compatible with common widths such as 16mm or 20mm. To verify manually, use a digital calliper and measure between the centre of a front lug and the corresponding rear lug.

For the Symphonette L2.304.0.71.0, alligator in fire red or cognac brown represents the classic aesthetic choice: this reptile's regular texture and fine scales convey luxury without burdening the compact case proportions. Aniline calf is a versatile alternative, particularly appreciated by those seeking a natural patina that evolves over time. For summer requirements, NATO straps in high-density cotton twill offer sporty elegance. Shell cordovan is the solution for those seeking superior longevity and beauty, with an unmistakable natural sheen.

To change the strap on your Symphonette, you must remove the spring bar pins. Obtain a dedicated tool: a spring bar tool or small flat-blade screwdriver. Insert the tool into the pin's groove and push gently downward to disengage it, then extract the pin from the case. Repeat on the other side. Next, insert the pins into the holes of the new 8mm strap and reposition them into the lugs, ensuring they sit fully. Consult a qualified watchmaker if you lack experience.

No. The 8mm lug width is specific and not compatible with other timepieces. Most watches use standard widths such as 16mm, 18mm, 20mm or 22mm. An 8mm strap designed for the Symphonette cannot be mounted on watches from other manufacturers or models, as the lug width and case geometry are entirely different. It is essential to order straps specifically engineered for 8mm lugs.

A high-quality artisanal leather strap for your Symphonette has an average lifespan of 3–5 years under regular use, with periodic cleaning and maintenance. Noble materials such as premium shell cordovan and alligator can exceed 7–10 years. Longevity depends on environment (sun exposure, humidity, water), frequency of use and care. A Casati Milano strap includes an 18-month warranty and is constructed for durability thanks to superior craftsmanship and carefully selected materials. The natural patina that develops over time is a virtue, not a flaw.
