In 1958, the Jaeger-LeCoultre Geophysic® became a standard for watchmaking. It's tough, withstanding tests for anti-magnetism, shock resistance, water resistance, and precision. Scientists involved in the International Geophysical Year were the original target audience. The new Geophysic watches maintain the classic look of the '58 models, but with updated dimensions. The round watch boasts a sleek design and houses a powerful self-winding movement.
