“Some of the earliest examples shown in advertisements from the Basel Fair of 1952 highlight the clock’s ability to “run for 24 hours from energy drawn from [only] one hour’s exposure to light”.

The launch was celebrated by a US tour, and the timepieces were displayed at prestigious venues such as the Museum of Science in Boston, Massachusetts.
