This is a stainless steel, 1950’s JUVENIA stainless steel chronograph measuring 36mm. in sparkling steel with a screw back. This watch offers simple and clean lines with a restored dial having 30 minute, 12 hour and constant seconds sub-registers. The very fine quality manual winding JUVENIA movement was just fully overhauled, cleaned, accurately and properly functioning. The original winding crown is still present. We love these simple and classic vintage chronographs!
