I have wound and tested for accuracy myself. Dating from the 1950s, this exquisite timepiece features a highly sought-after elongated \"marquise\" or \"navette\" (almond-shaped) case profile. It beautifully captures the graceful, jewelry-first design philosophy of post-war luxury and classic Hollywood style. Premium Vintage Kreisler USA Band Details: Manufacturer: Jacques Kreisler Co.
