F.P. JOURNE，鉑金年曆顯示自動上弦腕錶，配逆返日曆顯示，OCTA CALENDRIER，約2007年製，附後補證書、盒子及外包裝

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 triple calendar requires manual adjustment at the end of February only during the non-leap years.
