The Klokers KLOK 01 Heritage is a remarkable timepiece that uniquely blends historical inspiration with contemporary design. This unique timepiece draws its essence from the circular slide rule, an instrumental tool in mathematical calculations. It has been around since its inception in the 17th century and was notably used by aircraft pilots in the 1930s for complex navigational calculations. This inspiration is vividly reflected in the watch’s design, particularly in its time display mechanism. Innovatively, the KLOK 01 deviates from traditional watch designs by using three coplanar graduated discs. These discs represent hours, minutes, and seconds, all situated on the same horizontal plane and moving counter-clockwise. Time is read along the vertical axis at the top of the dial, offering a graphical, intuitive view of time. This design is a nod to the mathematical calculation tools, marrying simplicity with utility. A notable feature of the Klokers KLOK 01 Heritage is its interchangeability, facilitated by the patented Klokers key. This system allows the wearer to easily detach the watch case from its strap, offering the flexibility to change straps according to mood and style. This feature transforms the Klokers watch into an adaptable accessory, suitable for any occasion. The KLOK 01 Heritage is available in multiple color options, ensuring that there is a style to suit every preference. Its compatibility with a wide range of straps and interchangeable accessories further enhances its appeal.
