This is a vintage SWATCH CHRONO Watch: SIRIO  SCM101 , New in Clear Plastic Case with Papers.  1991/1992.

The tan leather band was made in France.  The spiral subdials are silver, but they can look charcoal, depending on the light. 

I am the original owner.  Never worn.  Everything is original including the battery, which will need to be replaced if you intend to wear it.

I am selling my Swatch collection.  Check out my other Swatch watches for sale on Ebay.  Happy to combine shipping fees.
