Beautiful vintage Certina Certiday Automatic, which is both optically and technically in neat condition. This is a Day-Date that tells both day and date. The Certina with its typical seventies case has a beautiful large size. The diameter without crown is 40 mm and the case is made entirely of stainless steel, and is a so-called 'clamshell' case The dial has a beautiful horizontally brushed structure with overlaid Certina logo. The hour markers are also overlaid and feature black details. These black details are also found in the hands. Additionally, the original Tritium has discoloured beautifully over the years. The Certina has a new genuine leather strap that was developed in Italy. It is suited up to 19.5 cm. The automatic Certina 25-652 movement runs very well and keeps excellent time. It winds well, both using the crown and by wrist movement, and the day and date change neatly. Therefore also a very good watch in technical terms! A unique Certina like this one, in this condition, will only increase in value. Certina is a luxury Swiss watch brand comparable to brands like Omega, Longines and Zenith.
