Although I'm not 100% sure. Band is black leather. This watch does have wear. The band has natural crease marks, and some cracking near the clasp. The face also has some light scratches and wear. I took pictures of all flaws. Please refer to them.
Made in Switzerland. Numbers on the back of the watch are '5106 0'. Certina Mechanical (Hand-winding) Wristwatches Certina hand-wound mechanical watches are both beautiful and traditional.
