Baselworld 2012: If you were to imagine a grand complication that would tantalize the eye of a lady, what would it look like? Answer: Ask Patek Philippe.

Ladies have always had a penchant for perpetuity and lasting value. They are fond of jewelry and especially in the past ten years have professed a growing interest in complicated mechanical calibers.

The new Ref. 7140 Ladies First Perpetual Calender is an ultra-thin (diameter of 35.1 mm and a height of 8.8 mm) self-winding mechanical wristwatch featuring a calendar mechanism that automatically knows the number of days in each month and also correctly displays the 29th of February in leap years. The precious array of flawless Top Wesselton diamonds (bezel with 68 diamonds totaling approx. 0.68 ct., clasp with 27 diamonds totaling approx. 0.20 ct.) as well as the lasting value of complicated Patek Philippe watches make this charismatic gem for the feminine wrist a treasured possession that will retain its contemporary allure for generations to come.

Personally, I like the 7140. Patek Philippe has done with this watch what they manage to do with all of their complicated timepieces: turn complicated in to simplicity. The dial, while busy, is easy to read. The 7140 is highly attractive.
