The present watch is an exceedingly rare and highly attractive representative of the Octa Calendrier family, the combination of the pink gold case and black mother-of-pearl dial rendering it a very unique look.
The Octa Calendrier was launched in 2005 and remained in production until 2014. It is the first wristwatch combining an annual calendar with a large date and a power reserve exceeding 120 hours.
The annual calendar is the third complication to be integrated in the Octa calibre, a calibre featuring a power reserve of over five days while keeping a very high degree of precision even when the watch is not worn.
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.
