Atmos 561

Though technically not a watch, the Atmos 561 needs to be mentioned. The Atmos clock is remarkable in that it does not require batteries, winding, or energy. The clock, which was created in 1928, is driven by a combination of gases, temperature, and air pressure.

The Atmos 561 is more exciting than ever with its new form and function, the transparency of the casing, the modernity of the movement, and its construction utilizing glass and metal. The renowned Atmos has been the official gift of the Swiss Federal government for many years, and it is held by some of the world's most distinguished men and women. Originality and simplicity are so perfectly matched in the 561 that it is a visual feast.

The 561, created to commemorate the model's anniversary, is an amazing clock as well as a fantastic ornamental and intriguing piece. Marc Newson, an industrial designer who has lately worked on Apple watch designs, created this iteration of the clock. Only 888 Atmos 561 by Marc Newson were produced.
