Each individual calibre must endure a battery of tests over several days, in five positions and at three temperatures. The exterior is just as seductive as the mechanics inside. A delicate pattern of waves flows from the centre of the dial, before making way for a more traditional Clous de Paris motif hobnail around the periphery, where mesmerising diamond hour-markers take their position. The case opts for a classic round shape, while a bracelet with alternating polished and satin-finish links lends the perfect final touch.
