Frequently asked questions

What is the lug width of the Longines Symphonette L2.307.4.87.0?

The lug width of the Longines Symphonette L2.307.4.87.0 is 13mm. This measurement is taken by positioning a calliper between the two inner lugs of the case, perpendicular to their axis. It is a specific dimension for compact, high-quality ladies' watches, compatible with a broad range of bespoke straps.

Which strap material is most recommended for the Longines Symphonette L2.307.4.87.0?

We recommend alligator for its uniform grain and proportional appeal to the compact case, or vegetable-tanned calf for those seeking softness and chromatic evolution over time. Shell cordovan suits those who value tactile memory and constructive density. Each choice should be evaluated against the dial, wrist size, and intended use context.

How do I change the strap on a Longines Symphonette L2.307.4.87.0?

Strap replacement requires two tools: a spring bar tool (or a thin screwdriver) and considerable care. Release the spring bar by compressing it laterally from one of the two lugs until the shoulder retracts and the bar exits its housing. Repeat from the other side. Insert the new attachments in the same manner, ensuring the spring bar is fully engaged on both sides.

Can I use a non-Longines aftermarket strap on my Symphonette L2.307.4.87.0?

Yes, provided the strap has been manufactured expressly for a 13mm lug width. We recommend custom, artisanal straps created by professionals who respect the case specifications and attachment geometry. A made-to-measure strap guarantees impeccable fit and constructive longevity.

How long does a natural leather strap last on a Longines Symphonette?

Lifespan depends on material and usage. Alligator and shell cordovan offer 5-7 years of resistance with ordinary care. Vegetable-tanned calf, being softer, requires greater attention and lasts 3-5 years. Regular maintenance (cleaning, controlled humidity) significantly extends useful life. The Casati Milano atelier provides an 18-month warranty on all custom straps.
