Longines Symphonette XL Roman L2.307.4.71.6

The case sits under a sapphire crystal, with feuille hands over the guilloché dial, and takes a 13 mm strap or bracelet.

The L2.307.4.71.0 is the same watch on a strap. The L2.307.0.71.6 keeps the ivory Roman dial and the bracelet and adds a diamond-set bezel, and the L2.307.4.57.6 is the steel bracelet watch with a black dial. The same ivory Roman dial on a steel bracelet comes in two smaller cases: the L, L2.306.4.71.6, at 21.9 mm, and the M, L2.305.4.71.6, at 18.9 mm.
