Audemars Piguet manufactured their first minute repeating wristwatch in 1907 for the renowned American industrialist John Schaeffer. This customised pioneer version was housed in a cushion-shaped case, the numerals on the dial were personalised with the letters of his name instead of numerals. In the early 1990s, Audemars Piguet launched the “John Shaeffer” limited edition series, paying tribute to the original “coussin tortue” or “cushion turtle” design.
