03/ STAYING POWER

Styled in a 1960s fashion, this watch is a classic looker – but it’s what lies beneath the cool exterior that matters. The precision of its automatic movement has been certified by the Official Swiss Chronometer Testing Institute, and its power lasts five days – stamina made possible by ultra-light silicon hairsprings, which sap away less energy than standard metals. Just like when you press 50kg instead of 90kg at the bench.
