Diameter excluding crown: 34 mm Jewels: 21 Strap material: Black, leather Strap brand: Certina Crown brand: Certina Case material: Stainless steel Buckle material: Certina, stainless steel Caliber: CAL 25-451 Great looking vintage watch from a premium Swiss manufacturer. Running, but very slow, needs a service. I do not have a relationship with a watchmaker and decided to sell this one to somebody who can get the service done with less fuss and bother - if that's you, and you are a fan of these vintage Certinas, this is one you will enjoy wearing. Purchased from an EU dealer on chrono24. Using a few of their pictures to supplement my images. Price: $399, plus $23 for conus shipping. Will ship to other locations if the buyer is willing to pay the additional costs over $23.
