Eterna “Twin Time Quartz” - Brevet mondial

Aesthetic perfection and technological performance meet in this, the world’s first ultra-thin watch-on-a-watch providing two distinct indications of the time. When closed, it displays its dressy face: an analogue dial (with hands). It opens to reveal its functional side: a digital display with second time zone, calendar and chronograph. Its aggregate thickness is a mere 4.5 mm - its analogue movement and digital module being, after all, the world’s thinnest in their respective categories. In white and yellow gold, set with diamonds.
