雅典表发布自己称“独创”万年历手表的万年历手表，Perpetual Manufacture.

全新手表搭载可以前后调整日期的原厂机芯UN-32

万年历作为一个经典的复杂功能，不仅考虑到月份是30天或是31天，还会辨别2月有28天，以及在每四年一次的闰年自动调整有2月29日，这就代表手表拥有1,461天的机械记忆。“独创万年历手表”将要在2100年进行第一次人手调校，因为在阳历上2100年本应为闰年，但却市面上大多数万年历机构没有2月29日，所以手表日期需要往后转一天。

只需轻松地沿顺时针或逆时针方向旋转表冠，便可以调整年份、月份、日期及星期四个窗口。此手表搭载的UN-32机芯设有第二地时间指示，轻按位于4点钟和8点钟位置的(+)(-)键，时针可以迅速前后调校至另一时区。当时针跨越国际日期变更线时，年份、月份、双窗口大日期及星期四个窗口皆会自动地同步前后调校，达至复杂机械手表的最高境界；而红色GMT箭头指针可指示原居地或第二地时间。

GMT指标则悬浮在24小时刻度内圈上。表壳直径43毫米，每只手表9点钟位置皆隽刻出厂编号，独一无二，18K玫瑰金及铂金表款各限量250枚。

Ulysse Nardin unveiled its latest perpetual calendar GMT “Perpetual Manufacture”

As the name indicates, this novelty is equipped with its in-house perpetual calendar movement.

As one of the classic complications of watchmaking, perpetual calendar movement can  identify not only the 30^th and 31th of the months, but also the 28^th and 29^th of February (leap year).  Most perpetual calendar watch will need to be adjusted by hand in year 2100, because as per Gregorian calendar that we are after, 2100 is supposed to be leap year, yet most perpetual calendar mechanisms can’t recognizie this based on the current version of calculation. It is necessary to adjust it by hand in factory for what so ever mechanical perpetual calendar watch to correct this date.

With the case of Ulysse Nardin, this adjustment can be fulfilled simply by pulling out the crown (to certain click) and turn. The UN-32 movement offers GMT function as well, and adjusting is done by means of two pushers (+) n (-)at 4 o’clock  and 8 o’clock respectively . These adjustments will even coordinated with the change of time zone.

The index of GMT is  ‘floating’ on the 24 hour marker, rose gold or platinum, case diameter is 43mm, serial number is engraved at 9 o’clock. 250 pcs for each metal.
