1950s Jaeger-Lecoultre Futurematic ref. E501

| | | mm

The Futurematic was a bold statement of technical confidence: the world’s first fully automatic watch without a winding crown. By moving the setting crown to the back, JLC achieved a perfectly symmetrical dial featuring a power reserve indicator and small seconds. The E501 is more than a watch; it is a mechanical curiosity from the "LeCoultre" golden era, designed never to stop as long as it stays on the wrist.
