万年历腕表常常让钟表迷着迷，其复杂机芯就像微型计算机一样，根据不同的月份和天数，自动调整闰年，显示正确的日期。Watches & Wonders 2023也包括了许多复杂功能腕表，无论是Piaget推出的超薄万年历，还是Vacheron Constantin带来的双面复杂巨作，都各具独特卖点。
伯爵Polo万年历超薄腕表
Piaget一直以超薄机芯而闻名。早在1960年，品牌推出的12P机芯，率先采用了微型摆陀技术，成为当时全球最薄的机芯。50年后，品牌以此为基础，推出了全新的1200P机芯。来到2023年，Piaget再次将1200P机芯升级，加入了万年历功能，机芯仅厚4毫米，命名为1255P机芯。
This movement is first introduced in the Polo perpetual calendar ultra-thin watch, with a thickness of only 8.65 millimeters. The emerald green dial is decorated with a straight grain pattern, with subsidiary dials at 9, 12, and 3 o’clock positions, displaying the date, month (including leap years), and day of the week, and a moon phase display at 6 o’clock position. The watch can accurately calculate the day of the week, date, and year until 2100.
江诗丹顿Les Cabinotier 阁楼工匠双月超卓复杂功能腕表
腕表搭载全新自制 2755 TMRCCQP 手动上链机芯，这枚机芯由 774 个零件组成，具有三问报时、万年历、精密月相和星空图等多项功能。江诗丹顿经典的逆跳显示功能亦保留，用以显示日期。
The dial design is unique, with a dual moon display in the central position. The dial is adorned with exquisite polished details, different from the usual design. The large-sized moon phase display window is located at the core of the dial, depicting the changes in the waxing and waning of the moon observed in the northern and southern hemispheres. The background of the moon phase display window is treated with PVD, presenting a vast deep blue night sky, and the surface of the moon is cut with micrometer-level precision stainless steel, creating a sparkling effect like stardust.
