We begin by presenting some of the previews of the next Sihh, with which the appointment is from 18 to 22 January. Among the stars of the Show is Audemars Piguet's Royal Oak, a watch that set the standard, imposing steel in haute horlogerie subservient to sport. Today, after having explored new horizons and new materials, the Royal Oak relaunches yellow gold in a version with a perpetual calendar with astronomical moon and indication of the number of the week during the year. The 5134 calibre is based on the previous model, the 2120 calibre, but has been enlarged to fit the updated 41-millimetre case. This new edition is partly inspired by the first Royal Oak Perpetual Calendar from 1984.
