Mid-century Jaeger-LeCoultre in steel
A Jaeger-LeCoultre from the 1940s, presented in a 37 mm steel case, exemplifies the restrained proportions and functional clarity of wartime and immediate post-war design. The original dial with mixed Arabic numerals and indices and a period-correct acrylic crystal speak to its authentic, utilitarian aesthetic. At its heart sits the manual-wind P478 calibre, a 15-jewel movement reflecting JLC’s long-standing commitment to dependable, well-finished mechanics. Recently serviced, this watch offers a historically minded collector a wearable piece that bridges mid-century manufacture and modern daily use with confidence.
