For the longest time, my wife has her eyes set on Girard Perregaux's Cat's Eye. Not only does GP represents her initials, she likes the unique shape of the watch.
The watch features an Annual Calendar in the form of the Zodiac calendar. The diamond marker at the 7 o'clock indicates month while the date disc is at the 1 o'clock position. The annual calendar feature is different from the perpetual calendar in that you need to adjust it for the month of February every year. Other than that, an annual calendar watch will automatically take into consideration the 30 or 31 days depending on the month. The moonphase is in a rather unusual position - towards the centre of the dial.
Overall, a pretty package that my wife is very happy with. And I am happy for her too.
