Established in Switzerland over 130 years and now part of The Swatch Group, Certina are a well respected brand. This watch we believe dates to the late 40's possibly early 1950's.
The Military style designed all steel case with a screw back, is in good condition, some surface scratches but nothing major, the dial equally has only slight  wear, the numerals are clear and visible. 
Inside the case is a 16 Jewel Lever KT304 Swiss Movement signed Certina. 
Cosmetically overall in good condition and running well.
