This is a vintage Omega Chronostop 145.009 which dates to 1970.

The watch has a stainless steel case which measures 34.65mm in diameter excluding the signed crown. For its age, the case is in good condition with some signs of wear.

The dial is in good condition for its age, with only light signs of wear. It has the original signed Omega crystal. 

The manual wind movement is running well and keeping good time for a vintage watch. 

The watch comes on the original Omega bracelet which is extra long. The minimum length is 19.3cm. If you need a shorter one, please look at my other listings. 

The watch comes in a vintage Omega box.
