Historical Significance & Design

The Ellipse line emerged during a golden age of design exploration in the 1970s, where watchmakers departed from traditional round cases in pursuit of distinctive aesthetics. The ref. 5002.42 is a prime example, featuring a beautifully sculpted oval steel case measuring 30.8mm in width and 39mm lug-to-lug—an ideal proportion that wears gracefully on the wrist.

Its bold, minimalist design is punctuated by the vibrant blue dial, a testament to Jaeger LeCoultre’s commitment to craftsmanship and innovation during the quartz crisis, when only the most refined mechanical pieces stood out.
