It dates from the 1970s, has a mechanical/wind-up 17 jewel movement, runs quietly, and keeps perfect time. It comes with a dark chocolate brown Hirsch Croco leather band.

The rectangular case measures 18mm (across the crown) x 27mm (lug to lug).
The crown is set with a synthetic blue sapphire.
It has a white dial with black Roman numeral markers and black hands.
It has a snap case which is not inscribed or monogrammed.
There are no papers or original case.
The band will fit a 5 1/2" to 7" wrist.
The crystal has no scratches but the dial has a scuff or spot of something at the bottom partially obscuring SWISS.
