Perpetual calendar Art Deco Mistral

Perpetual calendar of office art deco mistral. A perpetual calendar ephemeral date in chrome metal. The date displays the day of the month thanks to two small levers to be operated on its sides to scroll through the days. A rotary knob on the back allows you to scroll through the day of the week written in full letters. We change the month thanks to small plates printed on both sides. A few marks on the metal, a month label, cut at an angle on the edge.
