The Christophe Claret Aventicum is inspired by a gold bust of Roman emperor Marcus Aurelius unearthed in 1939 at Avenches, Switzerland. At the heart of this timepiece, Christophe Claret has placed a small scale reproduction of this bust in gold measuring only 3 mm high and micro-engraved to resemble as much as possible —considering the scale— the original bust from where it takes its inspiration.
