The Watch

In 1966 a small group of US inventors had the idea to create a revolutionary wristwatch: The watch was to be digital and the case had to reflect the new technology using a modern shape. By 1970, a first prototype had been presented to a curious show audience. People saw a wristwatch with a ruby red digital display which illuminated upon the push of a button.

In April of the following year the watches finally appeared in the first jewellery stores. Early available watches came in 18 Karat solid gold emphasising the sophistication and distinctiveness of the new technology. Ever since these digital LED watches have been providing the feeling of value and exclusiveness that only luxury timepieces can offer.

The Heritage

Following the tradition of the first digital timepieces, this drivers-style watch represents a case shape that does not conform to common watch-making. In comparison to conventional watches, the distinctive straight case design allows for a natural way of reading the time. Its contemporary drivers-style case and bracelet smoothly merge to form a single unit.

The Display

The front facing LED display is activated either by button or hands-free by a simple turn of the wrist. The LED’s readability and clarity outperforms every other way of displaying the time under poor light conditions (inside buildings, at night or even scuba diving).

The Crystal

The sapphire crystal is scratch proof under any conditions. Due to the self illuminating LED display there is no need for an additional anti-reflection layer (which is generally prone to scratching). In short, a watch crystal of outstanding toughness and durability.

The Clasp

The safety folding clasp with its bar and additional push button lock prevents accidental opening. Five pin positions allow for comfortable bracelet length adjustment.
