What I'm asked about the Longines Symphonette L2.307.4.57.0

What strap size does the Longines Symphonette L2.307.4.57.0 take?

The Longines Symphonette L2.307.4.57.0 needs 13 mm between the lugs. It's the size I've been fitting on it for years.

Can the strap on the Longines Symphonette L2.307.4.57.0 be changed?

Yes. It has spring bars between the lugs: with the right tool the strap comes off in a minute. If you'd rather not risk a scratch, I do it in the workshop.

Can I put a leather strap on the Longines Symphonette L2.307.4.57.0?

Yes, in 13 mm leather. On a 25 mm case a calf strap works every day; if you want something more, alligator.

Which strap do you recommend for the Longines Symphonette L2.307.4.57.0?

A 13 mm calf strap, for every day. I don't keep this size ready in the catalogue: I make it to measure. If you'd rather have something built on your wrist, the Casati atelier.
