Longines Lyre watches

The Longines Lyre is a slim steel watch made in sizes from 25 mm to 40 mm, with automatic and quartz versions side by side. Every one has a sapphire crystal, and the automatics are thin: 7.9 mm for the 38.5 mm, 8.7 mm for the 40 mm.

The automatics come at 25, 30, 35, 38.5 and 40 mm, the quartz models at 25, 32, 35 and 38.5 mm. Besides plain steel there are gold PVD and two-tone versions, and a red PVD finish on some 30 mm and 38.5 mm automatics. Dials are white, silver, champagne or blue, with Roman numerals as an alternative on the white dial, and many come on a bracelet as well as a strap.

The reference number spells out each Lyre. The first group gives size and movement: L4.360 is the 25 mm, L4.361 the 30 mm automatic, L4.960 the 38.5 mm automatic and L4.961 the 40 mm automatic, while L4.359 and L4.859 are the 32 mm and 38.5 mm quartz. The next digit gives the finish: 4 for steel, 2 for gold PVD, yellow or two-tone, 1 for red PVD. The pair after that gives the dial: 12 white, 11 white (usually with Roman numerals), 32 champagne, 72 silver, 92 blue.
