Note du spécialiste
The Octa Calendrier is the third complication to be integrated in the Octa automatic caliber. The integration of an annual retrograde calendar while maintaining the dimensions of the movement was another significant horological achievement. The instantaneously advancing day and month display is self-adjusting for months with 28, 30 and 31 days. The Octa annual calendar requires manual adjustment at the end of February only during the non-leap years.
