This is an unusual and hard to find Omega Speedmaster complicated Chronograph wrist watch. At 12 o'clock is a real-time 24 hour register. At 9 o'clock is a real-time seconds bit register. At 6 o'clock there is a 12-hour chronograph register. There are 4 center hands that include real-time hour hand and minute hand along with chronograph second hand and minute hand. At the 3 o'clock position there are day and date windows. The mint black dial reads OMEGA Speedmaster Automatic, Swiss Made. It has a tachymetre bezel ring under the crystal. It has an orginal Omega signed crown and 2 round chronograph buttons. This watch runs perfect and the chronograph returns to zero. The case and Omega signed band are stainless steel. The screw on case back is marked Omega Seamaster. The crystal is free of scratches. There is a very slight roughness on the very outside edge of the crystal in a few spots (hardly detectable). This is a desireable watch with an attractive, rugged 70's style case. You will want to wear this prestigious and collectible watch every day!
