The Challenge II is a sturdy wristwatch that measures 45 mm in diameter. This leaves enough space on the dial for two subdials, showing the date and day as well as an open balance wheel at 6 o'clock. This watch is powered by a reliable automatic movement.
Technical details Challenge II
Scratch-resistant sapphire glass
Sapphire is one of the hardest of all transparent materials. For watches, sapphire crystal scores highly, especially because of its scratch resistance and high resistance to shocks.
The classic date is found under the dial by means of a rotating disk. This is driven by the movement and moves one place forward at midnight, so that the current date is always visible in the cut-out in the dial.
Screws, and often other steel parts of watches, are blued using controlled oxidation. The refining process achieved by the brief heating not only results in the blue colour of the screws and is considered as being a high-quality and decorative element, but is also an expression of tradition.
Stainless Steel (316L) IP black
Stainless steel bracelets are especially popular because they require only a small maintenance effort, are resistant, and provide a secure grip particularly for larger and heavier models on the wrist.
