Founded in 1841, Leonidas started producing watches in Switzerland, gaining a reputation for quality chronographs. In the early 20th century, Leonidas supplied chronograph watches to military forces, especially the Italian navy during World War I. The present triple calander chronograph from circa 1950, housed in a refined 35mm stainless steel case, distils the essence of classic mid-20th century style.

The sleek two-tone silver dial provides a stage for triple calendar displays and bold subdials. An Italian day and month aperture at 12 o’clock tops moon phases indication at 6, while small seconds and 30-minute counters at 3 and 9 track time with symmetry. Gilt dot hour markers, leaf hands and a red crescent tipped date hand provide optimal legibility.

Leonidas showcases its heritage of quality Swiss watchmaking with this triple calendar chronograph, its mechanisms driving functions both practical and poetic. Bathed in mid-century charm, this rare and well-preserved complication offers enduring appeal for the discerning wearer.
