An early historic diver. 20ATM (200m), automatic, no date, bakelite bezel. The unpolished steel case (35mm diameter) has few marks from use. The SWISS T<25mc dial, hourmarkers and hands are mint! All lume is intact, even the triangle on the bezel. The movement has been serviced. It beats at 21600/h and is accurate within 15 seconds per day on the Timegrapher. This is a vintage you can use every day (treat every vintage watch carefully though). In short a vintage diver in very good condition!
