In its beautiful steel case – 39 mm and just 7.8 mm thick – the Master Ultra Thin Date watch has a strong personality sure to be appreciated by the adventurers of today. On the sunburst dial in an unmistakable blue-gray, every emblematic detail of the signature collection born of pure watchmaking tradition stands out, simultaneously forming a very well-balanced whole: polished case and bezel, slightly rounded lugs, slender trapezoidal hour markers and Dauphine hands. On the back of the watch, the in-house calibre 899, designed and assembled under the same roof at the Grande Maison, is beautifully finished: beveling, côtes de Genève and blue screws.
